Lawyer 'Tum' Petitions DSI to Investigate Online Gambling Networks

Prominent lawyer Sitra 'Tum' Biabangkerd has submitted audio evidence to the Department of Special Investigation (DSI) alleging links between a public figure and online gambling operations.

On September 21, 2026, lawyer Sitra Biabangkerd, widely known as 'Lawyer Tum,' formally requested that Thailand's Department of Special Investigation (DSI) launch an inquiry into alleged online gambling networks. According to reports from Matichon Online, Sitra presented audio recordings he claims feature a voice resembling that of 'Gun Jompalang,' a well-known social activist.

Sitra has urged investigators to conduct a thorough audit of financial trails, specifically requesting that authorities examine the assets and transactions of the activist's family members and close associates. The lawyer’s move is part of a broader effort to expose potential illicit financial activities linked to online betting platforms.

For residents and expatriates in Thailand, this development highlights ongoing high-profile efforts by authorities to crack down on illegal gambling, which remains a strictly prohibited activity under Thai law. While these allegations have generated significant public attention, it is important to note that the claims are currently under review by the DSI. No formal charges have been filed against the individual mentioned, and the authenticity of the audio recordings, as well as the validity of the accusations, remain to be confirmed through official investigation. Observers should await further updates from the DSI regarding whether they will proceed with a full-scale probe into these financial allegations.
