SINGAPORE - About 1.5kg of heroin was seized from under the seat of a Malaysian-registered motorcycle at about 7.30pm on Monday night at the Woodlands Checkpoint, said a joint statement from the Immigration & Checkpoints Authority (ICA) and the Central Narcotics Bureau (CNB).

The three bundles of controlled drugs, amounting to a street value of $155,000, were found by ICA officers in the cavities of the seat during a routine inspection.

The motorcyclist, a 28-year-old Malaysian, and the drugs were handed over to the Central Narcotics Bureau for further investigation.
