SINGAPORE - Central Narcotics Bureau (CNB) officers arrested 114 suspected drug offenders in an 11-day islandwide operation from June 18 to 29.

The operation, supported by the Singapore Police Force, covered areas including Anchorvale, Ang Mo Kio, Bishan, Bukit Merah, Bukit Panjang, Compassvale, Potong Pasir, Punggol, Toa Payoh and Yishun, CNB said in a statement on Friday (June 29).

In total, about 163g of Ice, 151g of heroin, 92g of cannabis, 30 Ecstasy tablets, 2g of ketamine and 138 Erimin-5 tablets were seized by the CNB during the operation.

One of the suspects, a 59-year-old Singaporean man, was arrested in the vicinity of Yishun Ring Road on June 18.

A raid was carried out at the suspect's hideout, which was a unit in the same vicinity.

The raid recovered a total of 138 Erimin-5 tablets, 28 Ecstasy tablets, about 70g of Ice, about 34g of ketamine, a small amount of heroin, a small amount of Ecstasy powder and about 5g of vegetable substances suspected to contain controlled drugs.

Two suspected drug abusers, a 29-year-old male foreign national and a 36-year-old local man, were also arrested within the unit. A 47-year-old Singaporean man, a suspected drug abuser, was also arrested at the void deck of a block in the vicinity.

In a separate case during the operation on Wednesday, CNB officers raided a unit in the vicinity of Yishun Avenue 4 and arrested two suspected Singaporean female drug traffickers aged 25 and 28.

Officers recovered about 9g of Ice and various drug-smoking apparatus within the unit.

Two children of the 28-year-old suspect, aged three and six, were playing outside the unit when both suspects were arrested.

They have since been handed over to their grandmother, the suspect's mother.

The 28-year-old suspect was also pregnant with another child and preliminary investigations found that she had continued to abuse Ice despite her pregnancy.

Investigations into the drug activities of all the arrested persons are ongoing.
