The man was initially charged with failing to stop for police, driving a motor vehicle without consent, resisting arrest, drug trafficking and going equipped for theft.

On Sunday, police searched a black Mercedes linked to the man and seized about 590 grams of heroin, about 170 grams of methamphetamine, 200 12-gauge shotgun cartridges and a sawn-off .22 calibre rifle.

The man faces more charges in relation to the seized drugs, ammunition and firearm.

Police say this is a significant disruption to the sale of thousands of “hits” of illicit drugs. They say there were more than 20 deaths last year believed to be as a result of opioids, including heroin, in the ACT.
