The Anti-Money Laundering Office's (Amlo) transaction committee says it has frozen 77 accounts worth Bt25.55 million linked to 64 alleged online bets, deputy secretary general Pol Maj Gen Romsit Wiriyasan said on Wednesday.
Romsit said Amlo investigated websites that allowed people to bet online on sport and the frozen account owners needed to account for their assets in court or risk the balance being seized by the state.
The websites included www.bkk999.com, www.fifa555asia.com, www.hlthailand.com, and www.sport4xonline.com, he said.
Romsit said it was just the first step and Amlo would further track the transactions to try to arrest the online gambling bosses.
He said Amlo sought cooperation from banks to monitor transactions via e-payment apps that might be used for online betting.
