Panthongtae "Oak" Shinawatra, a suspect in a money-laundering case, must return to the country and report to the court by March 26 after was granted permission to go abroad and attend the wedding of his sister in Hong Kong, a source said Thursday.
The Central Criminal Court for Corruption and Misconduct Cases approved his request for permission to leave the country late last year.
Mr Panthongtae is scheduled to attend the wedding of his sister Paetongtarn Shinawatra in March, the source said.
On Oct 10, last year, Mr Panthongtae, the son of fugitive ex-premier Thaksin Shinawatra, was indicted by the Office of the Attorney-General on charges of conspiracy and collusion in money laundering.
The charges stem from a 10-million-baht cheque he received which was tied to wrongfully approved Krungthai Bank loans of 9.9 billion baht which the state-run bank granted to subsidiaries of Krisdamahanakorn during Thaksin's administration.
The loans were approved despite the firm being listed as a non-performing debtor.
On Nov 5, last year, Mr Panthongtae pleaded not guilty to the charges when he was arraigned in the Central Criminal Court for Corruption and Misconduct Cases. He was later granted bail on the condition that he does not travel abroad without prior approval from the court.
