"We will also ask the Anti-Money Laundering Office [AMLO] to take further action," assistant National Police chief Suwira Songmetta said yesterday.
He said UFUN Thailand allegedly operated a pyramid scheme that has bilked Bt20 billion (S$830 million) out of 110,000 people. Arrest warrants have been issued for 12 suspects since news of the UFUN scandal broke, but only five of them have been arrested to date.
Among those in custody is Namonpan Thara-bundit, a top member of UFUN Thailand. Namonpan was nabbed on Thursday, while trying to leave Thailand via the border province of Nong Khai.
Police have found that she acquired many assets recently, including a luxury house worth at least Bt24 million in Bangkok's Bang Khen district and a Toyota Alphard sedan worth about Bt4 million.
Namonpan has told police that she tried to quit the business after noticing alleged irregularities in UFUN Thailand and claimed she told UFUN Thailand members in her team of her suspicions.
"UFUN Thailand management then got angry. My account at UFUN Thailand has been suspended. I can no longer conduct any transaction or withdraw any money," she claimed.
She has now advised UFUN Thailand members to lodge complaints with police to try to get their money back from the firm.
UFUN Thailand yesterday urged members, via Facebook, to exercise caution when digesting reports about the firm via social media. "Some ill-intentioned people have spread false rumours," it said.
Suwira said police were also trying to locate Namonpan's younger sister Hunsa Thara-bundit. "She's not at home. But we believe she is still in Thailand," he said.
Meanwhile, the Department of Special Investigation (DSI) is looking into whether UFUN Thailand's offences fall under its jurisdiction. "We will ask the Consumer Protection Police Division for further details," DSI deputy chief Pol Colonel Paisit Wong-mueang said.
