The Central Investigation Bureau (CIB) raided 63 locations across the country with suspected links to "Inspector Sua", a senior officer accused of involvement in a multi-billion-baht gambling network, and arrested an executive of the Pentor Group in connection with the accused officer.

Police searched the 63 premises which were allegedly linked to Pol Lt Col Wasawat Mukurasakul, known as "Inspector Sua".

Pol Lt Col Wasawat is being investigated for his alleged involvement in an online gambling network.

The police operations focused on companies serving as nominees for the accused officer and houses of his associates. Main targets were Pol Lt Col Wasawat’s residence and companies under the Pentor Group umbrella, mostly located at Soi Ram Intra 5 in Bang Khen district of Bangkok, according to a police source.

Another main target was a house in Bang Khen. The two-storey house belonged to a man identified only as Jiew.

A police investigation found that Jiew served as an executive of six firms under Pentor Group.

The officers found two cars - a Mercedes Benz and an Audi – parked in Jiew’s house. They also found one safe, luxury watches and many bank account books inside Jiew’s bedroom.

A criminal record showed Jiew was wanted under an arrest warrant for his alleged involvement in a call centre scam gang. He was indicted in a criminal case for persuading people into prostitution in 2011.

Earlier, former politician and whistleblower Chuvit Kamolvisit accused two senior officers, one of them Inspector Sua, of allegedly using their connections to run a large gambling network.
