Four suspected drug traffickers have been arrested by the Central Narcotics Bureau (CNB). The CNB in its operation also seized about 2.1kg of heroin worth $230,000.

On Wednesday, CNB officers were looking for two suspected foreign drug traffickers, who were believed to be distributing heroin consignments to local drug traffickers. At about 8.30am, one of the suspects, a 48-year-old Singaporean male, retrieved a plastic bag from another suspect, a 37-year-old Malaysian driver, from the passenger side of a lorry along Admiralty Road.

He then met up with another male, a 47-year-old Singaporean. Both were arrested by CNB officers shortly after in Marsiling. The 48-year-old suspect threw a plastic bag into the drain beside the pavement but it was quickly recovered and was found to contain about 730g of heroin.

CNB officers also followed the lorry from Admiralty Road to Clementi Loop, where they arrested the Malaysian driver. Another estimated 490g of heroin was recovered from the suspect's lorry. At about 9am the same day, CNB officers arrested the fourth suspect, another Malaysian, aged 35, who was meeting up with the 37-year-old driver. More than 960g of heroin was found in the fourth suspect's lorry.
