Eleven suspects arrested and two insurgents shot dead after Thai security forces smashed a militant cell behind Sunday’s Tak Bai police killings. Forensic evidence now links the group to the Bukeh Sami massacre that killed five Army Rangers.
An intensive police and military operation across Narathiwat on Wednesday ended with 11 suspects arrested, two insurgents shot dead and a major forensic breakthrough linking the group to July’s deadly Bukeh Sami checkpoint attack, as Thai security forces closed in on those responsible for Sunday’s Tak Bai ambush that killed two senior police officers and exposed what investigators believe is a wider militant network behind multiple attacks in the southern border provinces.
Following the deaths of two senior police officers on Sunday in Tak Bai, the Royal Thai Police and other security agencies have reported the arrest of 11 people and the deaths of two suspects after an intensive operation against a group linked to the southern insurgency.
Police say the investigation has already uncovered crucial forensic evidence linking the suspects to the July 22 attack on the Bukeh Sami checkpoint in Narathiwat. That assault killed five Thai Army Rangers and prompted a wider security crackdown across the southern border provinces.
Meanwhile, police sources said on Wednesday evening that several of those arrested are believed to have participated directly in the Bukeh Sami attack. Investigators now regard the two incidents as closely connected.
The latest findings also strengthen the broader investigation into insurgent activity across Narathiwat. Furthermore, the Bukeh Sami attack led to the cancellation of peace talks believed to have been scheduled in Malaysia.
Security crackdown after forensic evidence links Tak Bai ambush to deadly Bukeh Sami attack
The arrests and Wednesday’s fatal operation followed several days of coordinated military and police action after the deadly August 2 ambush in Tak Bai district. Provincial Police Region 9 Commander Pol. Lt. Gen. Piyawat Chalermsri said investigators have now identified 14 people connected to the attack.
So far, 11 have been apprehended for questioning. Three suspects remain under active pursuit. Separately, two suspected gunmen died during another security operation in Sukhirin district on Wednesday morning.
Pol. Lt. Gen. Piyawat said sustained pressure from police and military operations forced insurgents to abandon mountain hideouts before dispersing across Narathiwat. Investigators believe that movement ultimately exposed the group to detection.
In response, officers intensified operations throughout several districts. The commander also praised investigators from Tak Bai Police Station for their determination during the investigation and the subsequent manhunt.
The confrontation that triggered the operation unfolded shortly before midday on August 2 inside a palm plantation in Moo 6 of Phai Wan subdistrict, Tak Bai district. Earlier that morning, six officers from Tak Bai Police Station had completed a drug intelligence operation. Afterwards, they began the return journey using two police vehicles. Instead of taking the main route, they travelled through a shortcut crossing the plantation.
Drug search ends in deadly ambush after officers investigate isolated hut inside Tak Bai palm plantation
During the journey, officers noticed several people sitting beside an isolated hut. A white pickup truck was parked nearby. The surrounding area was largely deserted. Consequently, the officers decided to investigate. Three officers approached the hut while three colleagues remained beside the vehicles. Their task was to secure the road and provide cover if required.
At the same time, patrol commander Police Lieutenant Kittipong Srikhum moved around the rear of the hut. Moments later, officers heard movement from inside the building. They called out before moving closer. Without warning, two armed men opened fire with automatic weapons from inside the hut.
Police Sergeant Major Witthaya Chaiphromkaew was standing guard along the roadside. He was struck by gunfire and died at the scene. Almost immediately, the attackers fled around the rear of the hut.
There, they encountered Lieutenant Kittipong and Police Sergeant Major Amran Ha. A close-range gun battle followed. Sergeant Major Amran was killed during the exchange. However, Lieutenant Kittipong returned fire with his handgun. Police believe he wounded two attackers before they escaped into the swamp forest behind the plantation.
Soon afterwards, Tak Bai Police Station requested reinforcements. Military personnel, police officers and local administrative officials quickly surrounded the swamp forest behind the plantation. Their objective was to prevent the attackers from escaping the area. As part of the operation, officers searched the surrounding terrain while additional teams sealed nearby routes.
Police recover abandoned HK rifle as forensic evidence uncovers wider insurgent links across Narathiwat
The operation quickly produced results. Four people found near the scene were apprehended. Officers also recovered a disassembled HK assault rifle together with several magazines. Investigators immediately secured the area before beginning a detailed forensic examination.
Crime scene officers recovered 18 spent 5.56mm rifle cartridges, 21 spent 9mm pistol cartridges, one spent .32 calibre revolver casing and one .38 calibre revolver. Every item was submitted for forensic examination. Laboratory specialists then compared the evidence with material recovered from previous insurgent attacks across Narathiwat.
Notably, the forensic findings transformed the investigation. Ballistic analysis linked the recovered shell casings to insurgents operating in Chanae district.
Moreover, investigators found the same firearms had been used during the July 22 attack on the Bukeh Sami checkpoint in Ra-ngae district. That discovery immediately widened the scope of the inquiry.
Instead of investigating an isolated ambush, detectives concluded they were dealing with an established insurgent network operating across several districts. The evidence also connected the Tak Bai shootings with one of the deadliest attacks in the region this year. In turn, investigators expanded intelligence gathering beyond the original crime scene.
The Bukeh Sami checkpoint assault had already become a major security investigation. Five Thai Army Rangers were killed during that attack. Subsequently, peace talks believed to have been planned in Malaysia were cancelled. The killings prompted a significant increase in security operations across Narathiwat and neighbouring provinces.
Prime Minister and police chief order intensified operations against insurgent groups after attack
Following those developments, Prime Minister Anutin Charnvirakul instructed security agencies to intensify operations against insurgent groups. National Police Commissioner Pol. Gen. Kittirat Panpetch issued similar instructions.
Likewise, Deputy National Police Commissioner Pol. Gen. Samran Nualma, who commands the National Police Forward Operations Centre, ordered stronger proactive operations alongside military units.
Accordingly, the Internal Security Operations Command Region 4 Forward expanded operations throughout mountainous areas long believed to shelter insurgent groups.
Police believe sustained pressure forced members of the network to abandon those positions before moving into lower-lying communities. Investigators say that decision ultimately led them to the abandoned hut inside the palm plantation, where the deadly confrontation unfolded.
Investigators now believe the suspects had occupied the isolated hut for two days before the Tak Bai shooting. The building was normally uninhabited. According to police, the group chose the location after abandoning mountain hideouts under sustained security pressure.
By then, combined military and police operations had intensified across Chanae, Ra-ngae and neighbouring districts. Officers believe that pressure disrupted established insurgent movements and forced members of the network into increasingly vulnerable positions.
Sustained military pressure forced insurgents from mountain hideouts before the Tak Bai confrontation
Following the August 2 gun battle, investigators began reconstructing the group’s escape. Forensic officers examined the plantation, surrounding swamp forest and nearby routes. At the same time, detectives interviewed witnesses and questioned those detained at the scene. Gradually, a clearer picture emerged of the suspects’ movements after the ambush.
Evidence indicated that several wounded suspects fled towards Cho Airong district. Officers later discovered bloodstains, medical gauze and first-aid supplies at locations used during the escape. Those findings suggested injured gunmen had received emergency treatment shortly after the firefight.
Witnesses also confirmed that two wounded suspects were treated before being transported onwards. Police identified one of them as Abdulmuklis Puteh.
Investigators documented injuries to fingers, arms, legs and ankles among the wounded men. Those injuries matched the police account of the exchange inside the plantation. Police believe the wounds were sustained when Lieutenant Kittipong Srikhum returned fire during the confrontation. The findings also reinforced the conclusion that at least two gunmen escaped despite being injured.
Meanwhile, detectives traced the suspects’ movements beyond Cho Airong. Intelligence indicated the group had divided after leaving the plantation. One party of two travelled towards Cho Airong district.
Investigators trace wounded fugitives through blood trails, witness evidence and escape routes
Another group of three moved towards Ra-ngae and Chanae districts. Separately, investigators continued interviewing those already apprehended. Each interview added further detail to the suspects’ movements, support network and escape routes.
In parallel, forensic specialists continued examining weapons, shell casings and biological evidence recovered from the crime scene. Ballistic evidence was compared with previous attacks linked to insurgent groups operating across Narathiwat.
DNA samples were also processed as investigators sought to identify everyone involved in the ambush. According to police, the growing body of evidence steadily narrowed the search area.
Soon afterwards, officers received fresh intelligence concerning two wounded suspects. The information pointed to an unmarked house in Moo 5 of Sukhirin subdistrict, Sukhirin district. Police believed the pair had initially sought treatment before moving to the property. Consequently, a large-scale operation was prepared for the morning of August 5.
The operation involved investigators from the Narathiwat Provincial Police Investigation Division, Border Patrol Police Unit 44 and Ranger Regiment 11. Tactical officers from Unit 543 also participated. In addition, personnel from the 9th Air Force Task Force joined the operation.
Deputy National Police Commissioner Pol. Gen. Samran Nualma oversaw the mission, while Pol. Lt. Gen. Piyawat Chalermsri directed the wider investigation. On the ground, Pol. Col. Niyom Suwannakhong, Superintendent of the Narathiwat Provincial Investigation Division, led the investigative team.
Intelligence directs police and military force to wounded suspects hiding in Sukhirin district
Before taking action, officers established a complete cordon around the target property. Escape routes were secured while tactical teams moved into position.
As part of the operation, respected religious and community leaders were brought to the scene. Police hoped their presence would persuade the suspects to surrender peacefully and avoid further bloodshed.
However, those efforts failed. According to investigators, the suspects rejected repeated requests to surrender. Instead, police say they opened fire from inside the house. Officers immediately returned fire. A prolonged exchange followed and continued for more than 30 minutes. Security personnel maintained the cordon throughout the operation while preventing anyone from entering or leaving the area.
Only after the shooting stopped did officers enter the building. Inside, they found two dead men. Police identified them as 34-year-old Saman Mali of Sukhirin district and 23-year-old Abdulmuklis Puteh of Tak Bai district. Both men were believed to have participated in the August 2 attack on Tak Bai police investigators.
Investigators also recovered two police firearms from inside the house. One was a .38 calibre revolver believed to belong to Police Sergeant Major Amran Ha, who died during the Tak Bai ambush.
The second was a 9mm semi-automatic pistol believed to belong to Police Corporal Traithos Kulsanthawashiri of Tak Bai Police Station. Police believe both firearms were taken from officers during the August 2 attack before the suspects fled.
Post-mortems and DNA evidence back forensic case linking Sukhirin suspects to Tak Bai attack
Thereafter, provincial prosecutors and doctors from Sukhirin Hospital attended the scene before evidence collection began. Officers photographed the property and documented the positions of the bodies and recovered weapons. Afterwards, both bodies were transferred for detailed forensic examination before being released to relatives for religious ceremonies.
Post-mortem examinations revealed another important finding. Both suspects already had gunshot wounds before the Sukhirin operation.
Investigators documented injuries to fingers and legs consistent with wounds sustained during the Tak Bai confrontation. Those injuries supported earlier witness accounts and reinforced police conclusions that the same men had escaped from the plantation despite being wounded.
Background checks uncovered extensive criminal records. Police said Saman Mali was wanted under two outstanding murder warrants and two theft warrants. Abdulmuklis Puteh also faced outstanding warrants involving theft and drug offences. In addition, investigators linked him to security-related offences connected with insurgent activity.
Notably, forensic scientists made another significant breakthrough. DNA recovered during the investigation matched parts of the disassembled HK33 rifle abandoned inside the palm plantation hut after the Tak Bai shooting.
That finding strengthened the evidential chain linking the suspects to the original crime scene. It also reinforced the forensic links already established through ballistic examinations.
Investigators conclude one insurgent network carried out multiple attacks after forensics probe
By this stage, investigators believed the evidence pointed to a single operational network responsible for multiple attacks. The combination of ballistic evidence, DNA analysis, witness testimony and intelligence reports steadily strengthened that conclusion. Police said each new development reduced the group’s ability to conceal its movements or support structure.
Later on Wednesday, Narathiwat Provincial Police Commander Pol. Maj. Gen. Prayong Kotrasakha outlined the latest findings from the operation.
He said officers had pursued the group continuously since the August 2 attack that left two Tak Bai police officers dead and four others injured. According to the commander, the investigation never paused as officers combined forensic analysis, intelligence gathering and field operations to track those responsible.
Earlier that morning, police made one final attempt to end the standoff peacefully. Negotiators, supported by respected religious and local community leaders, repeatedly called on the suspects to surrender.
However, those efforts were unsuccessful. Instead, police said the suspects opened fire from inside the house. Officers then returned fire in self-defence. The exchange ended with both suspects dead inside the property.
Police link Tak Bai gunmen to Cho Airong attack as wider insurgent inquiry gathers momentum
Subsequently, post-mortem examinations confirmed that neither suspect had entered the Sukhirin operation uninjured. Both men already carried gunshot wounds sustained during the August 2 confrontation in Tak Bai. Investigators documented injuries to fingers and legs on both bodies. Those findings closely matched evidence gathered at the plantation and witness accounts collected during the investigation.
Pol. Maj. Gen. Prayong also confirmed that investigators had connected the same operational network to the attack on Cho Airong Police Station on May 28, 2025.
As a result, detectives are no longer examining the Tak Bai ambush as an isolated case. Instead, they are investigating a series of interconnected attacks involving the same insurgent group across Narathiwat province.
In addition, police widened their investigation into those suspected of assisting the gunmen after the Tak Bai attack. Officers identified people believed to have provided shelter, transport and other forms of support while the suspects attempted to evade capture. According to Pol. Maj. Gen. Prayong, 13 people have been detained as part of that inquiry. All are expected to face prosecution.
Investigators believe those arrests have substantially accelerated the wider investigation. Interviews with those detained have provided valuable intelligence concerning movement routes, temporary safe locations and escape plans used after the Tak Bai shooting. Furthermore, the information has enabled detectives to reconstruct the group’s movements with much greater accuracy.
Forensic evidence and manhunt continue as police pursue remaining fugitives and dismantle network
At the same time, forensic findings have continued to reinforce the intelligence picture. Ballistic examinations linked recovered shell casings to previous insurgent attacks. DNA evidence connected suspects to weapons abandoned after the Tak Bai confrontation.
Witness statements, medical evidence and recovered equipment also supported investigators’ conclusions. Together, police say the evidence presents a consistent account of the group’s movements before and after the ambush.
Separately, officers have continued searching for those who remain at large. Provincial Police Region 9 has identified 14 people connected to the Tak Bai attack. Eleven have been apprehended for questioning. Two suspects died during Wednesday’s operation in Sukhirin district. Three others remain under active pursuit as security operations continue across Narathiwat.
Police have also renewed warnings to anyone considering helping the remaining fugitives. Investigators said anyone providing shelter, transport or assistance to suspects will face prosecution under the law. Security agencies believe disrupting those support networks is essential to locating the remaining members of the group.
Tak Bai investigation provides crucial breakthrough in wider Bukeh Sami checkpoint attack inquiry
Meanwhile, investigators say the Tak Bai case has significantly advanced the wider inquiry into the Bukeh Sami checkpoint attack. Police sources indicated on Wednesday evening that some of those detained are believed to have participated directly in the July 22 assault. That attack killed five Thai Army Rangers and remains one of the most serious insurgent incidents in Narathiwat this year.
The forensic connection between the two attacks has become one of the investigation’s most important developments. Ballistic analysis first established similarities between recovered shell casings.
Afterwards, additional forensic work strengthened those conclusions. Detectives now believe both attacks involved members of the same operational network. Consequently, information gathered during the Tak Bai investigation is now assisting detectives examining the Bukeh Sami case.
The July 22 checkpoint attack also carried wider consequences beyond the immediate loss of life. Following the killings of the five Rangers, peace talks believed to have been due to take place in Malaysia were cancelled. Since then, security agencies have intensified operations across the southern border provinces in an effort to locate those responsible.
Government orders operations as security pressure forces insurgents from mountain hideouts
In response, Prime Minister Anutin Charnvirakul ordered stronger security operations. National Police Commissioner Pol. Gen. Kittirat Panpetch also instructed officers to increase proactive action against insurgent groups.
Likewise, Deputy National Police Commissioner Pol. Gen. Samran Nualma directed expanded operations through the National Police Forward Operations Centre. Those instructions formed the framework for the sustained campaign that ultimately forced suspects from mountain hideouts into lower-lying areas.
Police believe that sustained pressure became the turning point in the investigation. As insurgents abandoned traditional refuge areas, investigators gained opportunities to identify their movements.
Intelligence gathered during those operations eventually led officers to the hut in the palm plantation and later to the house in Sukhirin district. Each operation generated further forensic evidence and additional intelligence, steadily narrowing the investigation.
Notably, officers recovered two stolen police firearms during Wednesday’s operation. Investigators believe both weapons were taken from Tak Bai officers during the August 2 ambush. Their recovery strengthened the prosecution case while also providing additional forensic evidence for investigators.
Recovered weapons and forensic evidence strengthen case as Tak Bai murder investigation closes
Police also recovered the disassembled HK assault rifle abandoned inside the plantation after the original shooting. Forensic scientists subsequently matched DNA recovered from the weapon to suspects identified during the investigation.
Ballistic examination also connected recovered shell casings to earlier insurgent attacks in Narathiwat. Together, investigators say those findings have established clear evidential links between multiple crime scenes.
Two senior policemen killed in Tak Bai drug operation on Sunday. Detectives looking at insurgency links
By Wednesday evening, security officials described the investigation into the murder of the two Tak Bai police officers as effectively complete. Two suspected gunmen had been killed. Eleven people had been apprehended for questioning. Two stolen police firearms had been recovered. Extensive forensic evidence had also been secured from both operational sites.
Even so, police stressed that the wider investigation remains active. Detectives continue pursuing the remaining suspects while examining links between the Tak Bai ambush, the Bukeh Sami checkpoint attack and the May 2025 assault on Cho Airong Police Station.
Investigators believe the overlap between those cases has significantly accelerated efforts to dismantle the wider insurgent network operating across Narathiwat and Thailand’s southern border provinces.
