Packets of drugs and cartons of cigarettes were seized at the Woodlands Checkpoint on Monday night and early Tuesday morning.
In a statement on Tuesday, the Immigration and Checkpoints Authority (ICA) said that its officers and their counterparts from the Central Narcotics Bureau (CNB) and the police, found a 512g bundle of cannabis under the front passenger seat of a car. Another 52g packet under a spare tyre was found to contain "Ice".
The 59-year-old Singaporean driver was arrested on the spot. The ICA estimated the street value of the drugs is $27,300.
At about 4.45am, ICA officers uncovered a further 150 cartons of duty-unpaid cigarettes hidden in the rear compartment and under the back seat of a car during a routine inspection. The seized cigarettes were worth more than $17,000. The 41-year-old driver was referred to Singapore Customs for further investigation.
