Suspect hid heroin in the cleaner room
CNB officers arrested four suspected drug offenders, and seized about 1kg of heroin, among other drugs, in an operation on Sep. 19.
Officers observed a 48-year-old Singaporean man, a suspected trafficker, and a 30-year-old Malaysian man, meeting at a multi-storey carpark near Woodlands Avenue 6.
The Malaysian man was arrested and found with S$3,000 cash after the Singaporean man left the carpark in a van.
The van was later intercepted at the junction of Gambas Avenue and Sembawang Road. The 48-year-old Singaporean was arrested, along with another 49-year-old Singaporean also in the van.
Officers found 462g of heroin within the vehicle.
The 49-year-old suspect was later escorted to his workplace near Yishun Street 81, where he worked as a cleaner at a private residential estate.
Officers found about 563g of heroin, 34g of Ice and two Erimin-5 tablets inside the cleaner rest room.
A 51-year-old man, who is a suspected drug abuser, was also arrested in the process, and was found to be in possession of a small amount of Ice and some drug-taking utensils.
The teenager was found with 345g of cannabis
In a separate operation, an 18-year old Singaporean was arrested for suspected trafficking of cannabis at a void deck near Serangoon North Avenue 1.
