More than 2150 firearms have been seized by police following search-warrant activity in two operations last month.

In the first operation, following a joint investigation between ACT and NSW police, more than 2000 firearms and firearms parts were seized in Mitchell between March 4 and 6.

Police identified numerous breaches of the ACT Firearms and Prohibited Weapons Acts allegedly committed by a licenced firearms dealer. These included the apparent manufacture and possession of suppressors, possession of large-capacity magazines, prohibited imitation weapons, unregistered firearms, and inadequately secured firearms.

The second operation was conducted after an 80-year-old man was charged with family violence offences.

As a licensed firearms holder, the man was required to surrender his guns – with police subsequently seizing more than 150 firearms from his property in McKellar.

The officer in charge of the ACT Firearms Registry, Insp Dennis Gellatly, said police would always seize firearms when licence holders were doing the wrong thing.

“The Firearms Registry expects all licence holders to comply with their requirements, which are clearly outlined upon obtaining a firearm,” he said.

“Anyone who engages in criminal conduct can expect to have their licence revoked and their firearms seized.”
