Ong had skipped bail after he was initially charged in October 2021 with cheating. He failed to attend subsequent court hearings, and in September 2022, a warrant of arrest was issued against him.
Police said that they worked with foreign law enforcement counterparts to trace his whereabouts.
Ong was arrested by Thai authorities in October 2022 and jailed in Thailand for drug-related and immigration offences.
On Jul 30, he was released from prison and detained at the immigration detention centre before being deported to Singapore.
Ong’s next court mention was scheduled for Sep 2.
If found guilty, he may be jailed for up to two years, fined up to S$5,000, or both.
