On April 9, police and cyber police in Pattaya, Thailand, arrested Chinese national Pei Ming Si, identified by investigators as a key figure in an unnamed iGaming network with a turnover of $407.1 million.
The network operated over 239 websites and had more than 330,000 players across 31 provinces in China. The arrest was made at the request of the Chinese embassy in Bangkok, based on a warrant from the Public Security Bureau of Zhenjiang City, according to Chiang Rai Times.
Investigators link Pei to a transnational criminal syndicate operating in the Shwe Kok Ko zone of Myanmar, where he served as a leader. Since 2016, the syndicate's profits from illegal gambling have reached at least $74.9 million.
Pei had been on the run since May 26, 2024, fleeing to Laos on a Chinese passport, and returned to Thailand on August 15, 2025, using a passport from Saint Kitts and Nevis. His identity was confirmed through facial recognition technology, leading authorities to revoke his right to stay in Thailand.
He was transferred to the Investigation Department of the 3rd Immigration Bureau, and authorities are awaiting confirmation from the Chinese embassy for extradition. Thailand's Anti-Money Laundering Office (AMLO) has frozen 34 assets worth $257 million as part of the latest operation, bringing the total seizures in the case to 102 assets valued at $633.8 million.
