The CNB released a statement saying that they have seized about 7.5kg of illicit drugs worth about $400k.
A total of 3,820g or heroin, 2,934g of cannabis, 813g of Ice and an Erimin-5 tablet were deized in an operation that spanned multiple locations in Singapore.
Cash amounting to $9,370 were also confiscated.
2 Singaporeans and a Malaysian were arrested for suspected drug activities.
In one of the cases, CNB officers raided a residential unit near Edgedale Plains, where the 24-year-old Singaporean male occupant refused to let the officers in.
He then tried to evade arrest by scaling out of a window of the 17th floor unit.
The man was pulled to safety by the officers and a search was then conducted, where 6 packets of about 776g of Ice and 2 blocks of 1,914g worth of cannabis were found and seized.
At the time of writing, police investigations are still ongoing.
