Five suspected Singaporean drug offenders were arrested in operations across several locations this week, the Central Narcotics Bureau said.

The three men and two women, are aged between 19 and 34, Channel News Asia reports.

An assortment of drugs with an estimated street value of nearly S$410,000, including more than 1kg of crystal methamphetamine or “Ice,'' were seized.

Cash amounting to S$18,250 and multiple weapons including watermelon knives and a baseball bat were also seized.

The first arrest took place on November 16 when CNB officers apprehended a 34-year-old man near Somme Road in Little India. Three packets containing about 37g of Ice and 11 Ecstasy tablets were recovered from him.

The suspected drug trafficker was then escorted to his hideout in the same area where a search was conducted. Twenty packets containing about 1,276g of Ice, 11 packets containing about 342g of cannabis and 14 packets containing about 46g of ketamine were seized.

They also seized 161 Ecstasy tablets and fragments, 18 Erimin-5 tablets, six lysergic acid diethylamide (LSD) stamps, and a bottle of liquid suspected to contain gamma-hydroxybutyrate (GHB).

Various drug paraphernalia and S$14,000 in cash were recovered.

Later that day, CNB officers arrested a 25-year-old man, a 24-year-old woman and a 19-year-old woman near a hotel in the Balestier Road area.

The man put up a “violent struggle” to resist arrest, and “necessary force was used to subdue him”, said CNB.

A packet containing about 1g of Ice, a bottle of liquid suspected to contain GHB and a Karambit knife were recovered from the man. A search of his vehicle also found two watermelon knives, a parang and a baseball bat, along with various drug paraphernalia.

A Karambit knife was seized from a 25-year-old Singaporean.
