Thailand's Department of Special Investigation (DSI) expanded an investigation into illegal cryptocurrency mining networks allegedly run by Chinese financiers that laundered more than $300 million annually through illicit cash operations, following a series of raids in 2025 that seized 6,390 crypto-mining rigs and uncovered $29 million in electricity theft from the Provincial Electricity Authority (PEA). The transnational network utilized online gambling, call center scams, and cyber fraud to generate profits funneled through complex financial channels. The probe represents one of Thailand's largest state utility theft cases and has resulted in corruption charges against seven PEA officials and arrest warrants for eight suspects including four Chinese financiers.
DSI Seizures Uncover $29 Million Electricity Theft
The DSI's Technology and Cyber Crime Bureau dismantled three major syndicates in 2025, seizing more than 6,390 crypto-mining rigs. According to a local report, the operations stole nearly $29 million worth of electricity from the Provincial Electricity Authority (PEA). The DSI has forwarded two cases to the National Anti-Corruption Commission targeting seven electricity authority workers, one law enforcement officer, and 13 investors and suspected accomplices accused of facilitating the operation.
Investigators stated that profits from these tech crimes were laundered through corporate entities and bank accounts experiencing unusually high volumes of cash flow. The network allegedly hired Myanmar nationals to make daily cash withdrawals from Thai banks ranging from $910,000 to $1.5 million per day, totaling at least $307 million a year.
U.S. Secret Service Links Wang Yicheng to $61 Million Fraud Scheme
The DSI stated that U.S. law enforcement agencies provided intelligence tying a key figure in the operation, Wang Yicheng, to a major digital asset fraud scheme. The U.S. Secret Service previously seized more than $17.8 million in digital assets linked to Wang, part of a broader fraud scheme that caused nearly $61 million in total damages. U.S. Secret Service tracking revealed Wang Yicheng's group laundered $300 million annually from cyber scams.
Thai Authorities Issue Arrest Warrants for Eight Suspects
Thai authorities have issued arrest warrants for eight suspects, including four Chinese financiers and four Myanmar team members. They are seeking seven additional warrants and have summoned five others to face formal charges. DSI officials stated that the illegal use of electricity for cryptocurrency mining has evolved past simple utility theft, serving as a vital mechanism for international criminal syndicates to fund cybercrime and destabilize the country's economic and financial security. Prosecutors are currently preparing the case file for trial.
