The Department of Special Investigation (DSI) has pressed charges against Chanin Yensudchai, former CEO of the Stark Corporation, including money laundering and forging documents.
DSI acting director Yutthana Praedam said that the other charges are negligence, fraud, embezzlement and violating the Securities and Exchange Act, BE 2535 (1992).
Mr Chanin denies the charges so far, said Pol Maj Yutthana.
Pol Maj Yutthana said the DSI will work with the Anti-Money Laundering Office on any transfers of more than 8 billion baht that Mr Chanin made while escaping the warrant overseas, with the DSI focused on the criminal charges and Amlo focused on the civil ones.
Those who accept Mr Chanin's money and assets will be accused of money laundering, said Pol Maj Yutthana.
Wirun Chanthananan, director-general of the Office of the Attorney General's Department of Special Litigation, said that a prosecutor submitted his case to the Criminal Court on Monday.
Mr Chanin is the latest to be accused in the Stark case, joining 11 others, including five companies, according to Mr Wirun.
No one showed up to bail him out of detention on Monday.
Mr Chanin was detained at Bangkok Remand Prison, a source said.
The source said that the case caused huge damage to not only individuals but also the country's economic system.
The accounting and embezzlement scandal at SET-listed Stark is one of the country's largest corporate frauds in recent years, causing an estimated 14.7 billion baht in damages and affecting at least 4,000 investors.
On Monday, about 50 victims of the scandal gathered in front of the Office of the Attorney General to see Mr Chanin.
However, they failed to meet him as the police were concerned for his safety, so officers brought him straight to the court.
Mr Chanin, who fled more than eight months ago, returned to Thailand on Sunday and was escorted by DSI officials to its headquarters soon after his arrival.
Pol Lt Col Chakkrit Wisetkhetkan, director of the DSI's Bureau of Financial-Banking Crimes and Money Laundering, said that Mr Chanin's interrogation was done within two hours after his arrival at the DSI's office.
The questioning process mostly followed the Securities and Exchange Commission guidelines on the case investigation, with the predicate offences based on the Securities and Exchange Act and Money Laundering Control Act, BE 2542 (1999), he said.
He added that Mr Chanin's lawyer, Ruangsak Suksiangsri, had sent related documents to the investigators prior to the meeting.
The scandal came to light early last year after external auditors noticed discrepancies between reported figures and actual financial performance.
Investigators later found that Stark executives had orchestrated a scheme to present investors and stakeholders with a misleadingly positive financial outlook.
