Thai and Singapore police smashed a transnational online prostitution ring. Key suspects, including two Singaporeans, were arrested in Thailand. Over S$2 million in assets seized. Syndicate trafficked women to Singapore laundering earnings through complex networks.
A dramatic swoop by police forces in Thailand and Singapore on Tuesday and Wednesday smashed a lucrative prostitution ring operating in Singapore but orchestrated from Thailand. The latest arrest came on Wednesday when the financial kingpin of the operation was intercepted by Royal Thai Police officers as he disembarked from a flight at Suvarnabhumi Airport. He had just arrived from Singapore. At the same time, women working for the online network were arrested by police in Singapore and taken into custody in handcuffs. Police in both Thailand and Singapore also froze financial assets connected to the syndicate. In Thailand, ฿20 million was seized, while a further S$1.26 million was frozen in the city-state.
Two Singaporean men and one Thai national were arrested in Thailand this week for allegedly running a transnational vice syndicate. The arrests were the result of a joint operation by the Singapore Police Force (SPF) and the Royal Thai Police (RTP), conducted after more than a year of coordinated investigations.
The most recent arrest occurred on June 18, 2025, when Thai immigration police apprehended a 38-year-old Singaporean man at Bangkok’s Suvarnabhumi Airport. He had just arrived from Singapore on flight SQ 714. Acting on advance intelligence, Thai officers intercepted him immediately after landing.
Later he was identified by police as Mr Dexter.
He was wanted under multiple arrest warrants in Thailand. The charges include human trafficking, conspiracy to promote prostitution, advertising vice services and money laundering.

He was taken into custody without resistance and transferred to the Technology Crime Suppression Division for further investigation.
One day earlier, on June 17, Thai police arrested two other suspects linked to the same syndicate. One was a 36-year-old Singaporean man. He was picked up at his residence in Thailand. The third man arrested was a 50-year-old Thai national, believed to have assisted the group’s local operations.
The three arrests follow a year-long investigation into a network accused of recruiting foreign women and trafficking them to Singapore. These women were allegedly sent to work as vice workers under the syndicate’s management.
Authorities say the case dates back to early 2023 when Singapore police began investigating the sudden rise in foreign vice workers. Between April 2023 and May 2025, more than 70 such workers were arrested in Singapore. Many of them were linked to the same criminal group.
SPF said information gathered from those arrests led to breakthroughs. Investigators compiled evidence and worked with counterparts in Thailand to track down the syndicate’s leaders.

The two Singaporean men are believed to have played distinct but connected roles. The older man, arrested at the airport, is accused of handling the group’s finances. He allegedly used a complex web of bank accounts to transfer vice earnings from Singapore to Thailand.
The younger man, arrested at his residence, is believed to have provided logistical support for the syndicate’s overseas operations. He allegedly facilitated movement, housing, and communications for the vice workers sent to Singapore.
As part of the operation, Thai police seized over ฿20 million in suspected criminal assets. This included cash in multiple bank accounts, two condominium units, as well as laptops, mobile phones, hard drives, bank cards, and SIM cards.
Separately, SPF froze over S$1.26 million from the Singapore bank accounts of the 38-year-old suspect. Authorities believe the money was derived from vice operations and laundered through Singapore’s financial system.
According to Thai authorities, the syndicate also used online advertisements and messaging platforms to promote its services. Investigators believe these promotions were run by members operating outside of Singapore, including in Thailand.

The Thai Immigration Bureau said the man arrested on June 18 was flagged as a person of interest due to his travel patterns and digital footprint. They worked with multiple agencies to track and intercept him before he could leave the country again.
Following the arrests, all three suspects were charged under the Thai Criminal Code. They face prosecution for human trafficking, operating a vice syndicate, money laundering and promoting immoral acts.
Meanwhile, investigations in both Singapore and Thailand are continuing. Police expect to examine seized digital devices and financial records to identify additional associates and possible victims.
Officials from both countries praised the success of the joint operation. They emphasized that international collaboration was crucial to dismantling the syndicate.
Singapore’s Deputy Director of the Criminal Investigation Department, Senior Assistant Commissioner Yeo Yee Chuan, thanked Thai authorities for their cooperation. He said Singapore remained committed to working with regional partners to prevent the exploitation of women and disrupt criminal networks.

Thai police also highlighted the importance of intelligence sharing. Police Lieutenant General Jirabhop Bhuridej, Commissioner of Thailand’s Central Investigation Bureau, noted the professionalism of officers on both sides. He described the arrests as the result of “persistent coordination and accurate information exchange.”
The RTP added that the crackdown reflects Thailand’s broader efforts to prevent human trafficking and vice-related offences. The Immigration Bureau, in particular, has ramped up monitoring of foreigners suspected of involvement in such crimes.
As the investigation progresses, authorities will examine banking trails and seized communications to identify others connected to the group. Additional arrests may follow in both countries.
This latest development comes amid rising concern over transnational crime in Southeast Asia. Syndicates increasingly use digital tools and financial networks to operate across borders. That has made regional police cooperation more essential than ever.
Although this particular syndicate appears to have been severely disrupted, police stress that enforcement must continue. They plan to remain vigilant in both detection and deterrence efforts.

In the meantime, the three suspects remain in Thai custody. Their legal proceedings will be handled under Thai jurisdiction, with possible extradition requests subject to further developments.
Officials say more details will be released in upcoming briefings, including findings from the analysis of seized digital material.
With more than S$2 million in assets already frozen or seized, investigators are also working to trace the full extent of the syndicate’s financial networks. Forensic accountants and digital analysts have been brought in to support that effort.

While the SPF and RTP have called the joint operation a success, both sides agree that the fight against transnational vice crime is far from over. They pledged continued cooperation to ensure that syndicates exploiting vulnerable people across borders are brought to justice.
Surprisingly, prostitution in Singapore is not illegal. However, living off immoral earnings is, in addition to human trafficking.
In Thailand, however, all activities linked to prostitution are illegal. Consequently, it looks like the kingpins of this online prostitution empire are facing prosecution and jail time in Thailand. In addition, the operators face money laundering charges under tough Thai laws.
