Thai cybercrime police have arrested one of the country’s best-known anti-corruption campaigners, Atchariya Ruangrattanapong, in connection with an online boxing gambling investigation involving a network that allegedly generated more than THB1 billion ($29.6 million) in turnover.
The activist, a longtime and vocal critic of police corruption, denies all the charges and says the case against him is fabricated. Atchariya was arrested shortly after noon on Saturday, October 3rd, near the Om Noi boxing stadium in Samut Sakhon, under a Criminal Court warrant issued the previous day. He faces charges of public fraud, money laundering, and illegal electronic betting on boxing, along with offenses under the Computer Crime Act.
Officers from the Cyber Crime Investigation Bureau (CCIB) questioned him for more than four hours before transferring him to Thung Song Hong Police Station. He was due to appear before the Criminal Court on Chaeng Wattana’s Ratchadaphisek complex on Monday, October 5, where investigators were expected to seek his remand.
According to Police Maj Gen Prasong Chalermphan, commander of CCIB Division 1, the case grew out of a wider investigation into the “Muay Pak Yok Variety” online Muay Thai betting operation. In March, police raided six properties in Bangkok’s Bueng Kum district, arrested six suspects, and seized 245 mobile phones along with assets exceeding THB6.3 million ($186,000).
Investigators said the network’s financial turnover topped 1 billion baht. As police followed the money trail through the network’s administrators and associated accounts, they said it eventually reached Atchariya and accounts tied to his Crime Victims Assistance Club (also rendered as the Help Crime Victim Club).

Police allege they identified 212 transactions totaling more than THB40 million ($1.18 million) linking Atchariya to accounts uncovered in the gambling probe. Investigators said his personal account recorded 1,196 transactions worth more than THB191 million ($5.65 million), while the club’s account showed 5,140 transactions exceeding THB168 million ($4.97 million), combined turnover of more than THB359 million ($10.6 million). Police stressed that these are overall account movements rather than established gambling proceeds, and are concentrating on the 212 flagged transactions. No court has ruled that any of the sums represent criminal proceeds. Police also said Atchariya held sole withdrawal authority over the club account.
Pol Maj Gen Siriwat Deepo, a deputy Royal Thai Police spokesman, rejected suggestions that the investigation amounted to harassment, saying the case flowed directly from the March crackdown and the financial evidence uncovered since. On the separate fraud allegations, police said donors who transferred money to Atchariya’s organization believed the funds would be used to help crime victims.
Atchariya denied every charge. He said the club’s account, which he noted had operated for 12 years, was entirely separate from his personal finances, and that all the transactions under scrutiny had legitimate explanations. He disputed the fraud claim centering on THB414,000 baht ($12,300), saying 12,000 baht involved payments connected to a religious ceremony and a personal gift, while THB400,000 was a part-payment against an agreed 1 million baht fee for investigative work into suspected nominee companies in Phuket. He questioned the timing of the warrant – issued Friday, with the arrest the next day – and said he believed powerful figures within the police wanted him imprisoned, though he stopped short of naming anyone. No independent evidence has established that claim.

The arrest is notable because of who Atchariya is. For more than a decade, the Surat Thani-born former construction businessman turned legal campaigner has been among Thailand’s most recognizable independent crime fighters, founding the Crime Victims Assistance Club in 2009 and building an aggressive, confrontational investigative model that repeatedly put him at odds with the Royal Thai Police. His recent campaigns include high-profile interventions in the death of actress Nida “Tangmo” Patcharaveerapong, allegations of corruption at a Bangkok immigration detention center involving Chinese scam suspects, and a September claim to parliament that dozens of court arrest warrants had been forged.
Crucially for how the case is read, much of Atchariya’s campaigning has targeted the cyber police themselves. He is the source of widely cited claims that some officer networks collected hundreds of millions of baht a month from gambling operations, and he faces a pending defamation suit from a senior cybercrime commander over televised allegations that cyber police took payments from gambling operators. Saturday’s arrest is also his second this year: in April, he was arrested and granted bail of THB400,000 in a separate case alleging he attempted to extort THB2.5 million ($74,000) from an immigration police colonel, a prosecution he says followed his attempts to expose misconduct.
The gambling case is separate from that extortion matter, and the police position is that it rests on financial evidence rather than Atchariya’s activism. Atchariya’s position is that legitimate transactions are being recast as criminal money. Those competing accounts now head to the Criminal Court, where the evidence has yet to be tested.
