An attempt by a suspected drug abuser to bribe himself out of trouble on Sunday failed when a Central Narcotics Bureau (CNB) officer rejected the $13,300 he offered to let him off the hook.

The bureau said in a statement on Tuesday that officers from the Immigration & Checkpoints Authority (ICA) at Woodlands Checkpoint had stopped a Singaporean Chinese male for a routine check at the arrival Car zone on Sunday at about 11.55pm.

The 48-year-old suspect was subsequently referred to CNB for follow-up investigation into an offence of suspected drug abuse.

While waiting for his urine test to be conducted, the suspect offered all the money in his possession as bribes to the male CNB officer.

The suspect had about $13,300 in both Singapore and Malaysia currency.

The CNB officer rejected the bribe and a police report was lodged.

The Corrupt Practices Investigation Bureau (CPIB) is currently investigating.

Meanwhile, investigations into drug consumption charges are also underway against the same suspect.

Director CNB Ng Ser Song praised the CNB officer for his honesty, saying: "This officer exemplifies the Bureau's values of professionalism and integrity, and our zero tolerance towards corruption. We will report any attempts to bribe our officers."
