- Thai Immigration Bureau officers and South Korean police arrested 10 suspects, eight South Koreans and two Chinese nationals, in Bangkok on 19 October 2026, according to The Nation.
- Police allege callers posed as senior prosecutors and that the network also ran romance scams; The Nation says losses were put at hundreds of millions of baht.
- The Immigration Bureau revoked all 10 visas. No charges or court proceedings have been reported.
- South Korean voice phishing losses hit a record 1.2578 trillion won in 2025, according to The Asia Business Daily.
Thai Immigration Bureau officers and South Korean police arrested ten suspects in raids on three Bangkok locations on 19 October, The Nation (Thailand) reported on 20 October. Eight are South Korean and two are Chinese. Police allege the group ran a prosecutor-impersonation and romance scam operation aimed at South Korean victims.
The dating angle is indirect. The Nation names no dating app or platform, and describes the romance element only briefly. Operators should still read it, because it shows how romance fraud can be organised off-platform.
The DII Take
This is a scam-industry story with a romance strand, not a dating story. What matters for trust and safety teams is the allegation of trainers, scripts and separated work zones: romance fraud as a managed process, not a lone opportunist. Platforms can tighten their own defences, but the operation described here sits largely outside them.
What police allege
According to The Nation, callers pretended to be senior prosecutors and threatened their targets, sending them forged arrest warrants and fake evidence that accused them of money laundering. Investigators also alleged the network built relationships before sending fraudulent links to steal money.
Preliminary inquiries indicated the two Chinese suspects acted as leaders and trainers, The Nation reported. Callers could dial more than 50 numbers an hour, according to Pol Lt Col Sittimon Soipooraya of the Immigration Bureau's Investigation Division.
The Nation says officers seized more than 10 computers and phones. Bangkok Post put the figure at 13 computers and 21 mobile phones, and losses at more than 100 million baht.

Regulatory Monitor: what to watch
The Immigration Bureau has revoked all ten visas and is coordinating with South Korean authorities on tracing transactions and transferring the suspects for prosecution. The suspects entered on tourist visas, The Nation said, and the commissioner ordered a nationwide crackdown on visa overstayers.
Korean police said romance and investment chat-room scams numbered 1,127 cases in August 2026, with losses of 58.4 billion won, the lowest since the task force began. In the US, the FTC's April 2026 data spotlight says nearly 60% of people who reported losing money to a romance scam in 2025 said it started on social media.
- Romance fraud described in the Bangkok case is allegedly run as a trained, scripted operation, which raises the bar for platform-side detection.
- Watch whether South Korean prosecutors file charges and whether the romance element is tied to any named platform; none is named so far.
