Thai investigators have issued an arrest warrant for a Chinese businessman believed to be the central figure in a transnational criminal operation that stole tens of millions of dollars of electricity to power illegal coin-mining facilities, then used the proceeds to launder money flowing from telephone scams and illegal gambling on a scale of more than $300 million a year.
The warrant for Wang Yicheng was among eight issued on the 22nd of June by Thailand’s Department of Special Investigation, the country’s equivalent of a federal criminal agency. Four of the eight suspects named are Chinese nationals and four are from Myanmar. Investigators say they are seeking warrants for a further seven people and have summoned five additional individuals to answer formal charges. Wang, who had been based in Bangkok, is believed to have left the country and is being treated as the primary fugitive in the case.
The investigation began after a series of raids carried out in 2025 that broke up three separate criminal networks operating illegal coin-mining sites across Thailand. Those raids resulted in the seizure of 6,390 pieces of specialist computing hardware used to generate digital currency. Investigators from the agency’s technology and cybercrime division began working backwards through the financial trails those operations had left behind and found that what they had uncovered was not simply an electricity theft case but a sophisticated system for moving illicit money through the Thai banking system and beyond.
To understand what the network was doing, it helps to know how the fraud operated at each stage. At the base level, criminal groups were connecting to the national electricity grid without authorisation and drawing power to run large numbers of computing machines in warehouses and industrial buildings. Those machines performed the calculations needed to generate units of digital currency. Generating digital currency this way requires enormous amounts of electricity, which is why the theft of power was central to making the operation financially worthwhile.
The currency generated was then used not for legitimate investment or trading but as a vehicle to move money that had already been obtained through crime. Investigators say the wider network ran telephone fraud operations of the type sometimes called pig butchering, in which victims are cultivated over weeks or months through messaging applications before being persuaded to transfer money to what appear to be investment platforms. Once the money arrives, it disappears. The proceeds from those scams and from illegal online gambling were fed into the mining operation and moved through digital currency transactions, making the original source of the money harder to trace.
To turn the digital currency back into cash, the network employed couriers, mostly Myanmar nationals, who withdrew between 30 million and 50 million baht in physical cash per day from Thai bank accounts, equivalent to between roughly $900,000 and $1.5 million every day. Multiplied across the year, investigators put the total annual financial flow through the operation at more than 10 billion baht, or approximately $300 million.
The damage to Thailand’s state electricity authority was calculated separately. Investigators estimated the theft of power from the national grid at more than 953 million baht, equivalent to around $29 million, making it one of the largest acts of utility theft in recent Thai history. The inquiry also exposed what the investigators described as complicity among people who should have been preventing it. The Department of Special Investigation forwarded two sets of evidence to the National Anti-Corruption Commission concerning seven electricity authority officials, one law enforcement officer and 13 investors or alleged associates accused of helping the network access power supplies and avoid detection.
Wang’s name had already appeared in American criminal investigations before the Thai warrants were issued. As Reuters reported, the United States Secret Service previously seized more than $17.8 million in digital assets connected to him as part of a separate fraud case in which total losses were estimated at more than $61 million. American investigators had earlier traced funds from a fraud victim in the United States to a digital currency account in Wang’s name, which was linked to phone scam operations in Southeast Asia. A crypto account associated with him had reportedly received more than $90 million over recent years. His case has attracted additional attention since investigative reporting in late 2023 connected him to the broader ecosystem of fraud compounds operating across Southeast Asia, particularly in border regions where criminal organisations recruit and control workers to run online scam operations at industrial scale.
The arrest warrants mark a significant escalation in Thailand’s response to what has become a regional crisis. Over the past two years, Southeast Asia has emerged as one of the most active zones in the world for online financial fraud, coin-mining crime and the laundering of proceeds through digital currency networks. Criminal networks have exploited weak regulatory enforcement in border areas and the relative ease with which digital currency can cross jurisdictions without triggering the controls that apply to conventional bank transfers.
Thailand has increased cooperation with law enforcement agencies in other countries as part of its response, and prosecutors are preparing the full case file to bring the matter to trial. Whether Wang Yicheng can be located and returned to face those charges depends on where he is and on what extradition arrangements exist between Thailand and that country.
