SINGAPORE - Heroin weighing 936g and 147g of 'Ice' were seized in an operation on Thursday to nab a suspected drug trafficker around Tech Whye Lane.

Cash of S$1,000 was also recovered, said the Central Narcotics Bureau (CNB) in a statement on Friday. The street value of the drugs is estimated to be more than S$90,000.

The amount seized is enough to sustain the addiction of about 440 heroin abusers for a week, said CNB.

During the operation, CNB officers arrested a suspected Singaporean drug trafficker and male Malaysian suspected drug offender.

About 466g of heroin was recovered from the 48-year-old suspect. A subsequent search of his residence in the area recovered about 12g of heroin and 10g of 'Ice'.

CNB officers also searched and recovered about 25g of 'Ice' and some drug utensils on the 33-year-old Malaysian suspect.

A search of his motorcycle which was parked in the vicinity recovered another 458g of heroin, 112g of 'Ice' and cash of S$1,000.

Investigations are ongoing.

Under the Misuse of Drugs Act, traffickers face the death penalty if the amount of diamorphine (or pure heroin) trafficked exceeds 15g, which is enough to feed the addiction of about 180 drug abusers for a week.
