Police are launching a probe against a local superintendent believed to be behind the Saipay69 gambling site.

A complaint was made by Atchariya Reuangrattanapong of the Help Crime Victims Club who met the Cyber Crime Investigation Bureau (CCIB) to follow up after he asked CCIB police to check 17 gambling websites on Wednesday.

Mr Atchariya alleged these websites showed ties to numerous police officers, as well as the owner of a football club in the north of the country. They also sold online lottery tickets and even illicit drugs, he said.

Money from the online gambling networks was also found to have been transferred in the form of bribes to the Department of Special Investigation (DSI) and the Anti-Money Laundering Office (Amlo), he claimed.

"That's why the investigation into the networks' transactions failed to make much progress. Each website has at least 10 billion baht circulating in their bank accounts," Mr Atchariya said. He claimed to have a list of more than 100 police officers with ties to gambling networks.

Furthermore, he said he had clear evidence indicating that some officers were operating the sites themselves. He said he would hand over the list of officers to the RTP on Monday.

Police are investigating an allegation against a superintendent in the East after another suspect showed financial transactions linking him to Saipay69.
