Thai police raided dozens of locations across the country as they investigated suspects linked to call centre gangs and casinos in Cambodia.

The Cyber Crime Investigation Bureau on Tuesday stormed seven properties in Bangkok and the border province of Sa Kaeo suspected of being part of a large scam network operated by 71-year-old Cambodian gambling tycoon Kok An.

Footage shows the police squad barging into a sprawling luxury home in Bangkok believed to be owned by one of Kok An's daughters.

Police said the casino kingpin's three children, Juri, Phu Cherlin, and Kittisak, were also wanted over alleged links to the transnational fraud organisation, which reportedly runs multiple scam bases in Poipet, Cambodia, including the Crown Casino Resort, the HI-SO building, a 25-storey tower, and an 18-storey high-rise.

Authorities had earlier raided 19 sites where they seized more than 1.17 billion baht (26.9 million GBP) in assets on July 8.

Police Lieutenant General Trairong Phiewphan, commissioner of the Cyber Crime Investigation Bureau, said: 'Our goal is to seize all assets to redistribute them to victims and show the world that Thailand is seriously cracking down on call centre gangs.'

Officials said the network carried out hybrid scams, call centre fraud, and money laundering using mule accounts and digital currencies.

Thai nationals were lured into the operation under false pretenses like fake job postings, before being coerced into opening mule accounts. They are often illegally detained and forced to undergo facial recognition scans to authorise transactions.

Kok An, a close associate of Khmer Rouge slayer Hun Sen, is still at large.

Police General Thatchai Pitaneelaboot, director of the National Cybercrime Suppression Center, said police were seeking an Interpol Red Notice for his arrest. He said: 'Any Thai citizens found collaborating would face maximum penalties as traitors.'

The Department of Provincial Administration, under the Interior Ministry, said it has also launched an investigation into how Kok An's children were able to obtain Thai national IDs despite being Cambodian nationals.
