The announcement comes after authorities across Asia, Europe and the United States targeted Cambodia’s Prince Holding Group and its global business network with asset seizures and freezes worth billions of dollars.
In October, US authorities indicted Prince’s Chinese-born founder Chen Zhi, accusing him of presiding over forced labour camps in Cambodia where trafficked workers conduct online scams.
Anutin told reporters on Wednesday that alleged scammers targeted with asset seizures valued at more than $300mn were “among the big ones”, including Chen, a Cambodian senator and two Thai nationals.
“All those responsible must be brought to justice under the law,” the prime minister said.
Thailand’s Anti-Money Laundering Office said on Tuesday it had seized around 100 items belonging to Prince’s Chen worth B373mn, including land, cash, luxury goods and jewellery.
Authorities said they had also confiscated assets worth nearly $15mn from Kok An, a Cambodian senator, businessman and ally of former Cambodian leader Hun Sen.
Approximately $290mn in assets were seized from two Thais with suspected links to scam operations.
Anutin did not say when the seizures occurred.
Cyber-scam operations have mushroomed across Southeast Asia, often operating from unassuming office blocks or warehouses where con artists target internet users living all over the globe.
Some scam workers go willingly to the cyberfraud hubs, while others are trafficked and held in prison-like conditions.
Britain has also frozen business and London property assets worth more than $130mn and linked to Chen’s network, while Taiwan, Singapore and Hong Kong each swooped in with seizures as high as $350mn.
The US Justice Department in October called Prince Group “one of Asia’s largest transnational criminal organisations”, and seized around $15 billion worth of bitcoin that US authorities alleged were criminal proceeds from the company’s networks.
Prince this month denied that it or Chen had committed any crimes.
