SINGAPORE - The Central Narcotics Bureau (CNB) arrested three suspected drug traffickers in an operation on Tuesday (Sept 5).

About 2kg of cannabis and 466g of heroin worth over $51,000 were seized, CNB said on Wednesday.

CNB said its officers were deployed in the vicinity of Woodlands Town Garden's carpark on Tuesday morning to observe a suspected drug trafficker.

The suspect, a 29-year-old Singaporean man, was seen arriving in a car at around 11am. A male motorcyclist was subsequently seen approaching the car and handing over a bag to the suspect.

The car then left the carpark while the motorcyclist picked up another man a short distance away.

Both men, who are Malaysians aged 26 and 21, were arrested by CNB officers before they could leave the carpark.

Another party of officers arrested the Singaporean suspect when his car stopped at the junction of Jalan Toa Payoh and Upper Serangoon Road.

The drugs - packed in various bundles - were recovered from the car's front passenger area. Cash of more than $4,000 was also seized.

Investigations into the drug activities of all three suspects are ongoing.

In a reminder to the public, CNB said cannabis is a Class A controlled drug listed under the Misuse of Drugs Act, and that unauthorised consumption, possession, trafficking, import, export of any such drugs is an offence.

Those convicted of trafficking in more than 500g of cannabis could face the death penalty.
