The Chinese national corruptly offered S$100 to them, as well as a third officer who later arrived, so that they would not arrest him, said the Corrupt Practices Investigation Bureau (CPIB) in a news release.
The officers did not accept the bribe, and reported the case to CPIB.
Han was charged in court in June 2020 for offences under the Prevention of Corruption Act.
Anyone who is convicted of a corruption offence can be jailed up to five years, fined up to S$100,000, or both.
