The arrests were made over two days in Operation Prodigy, which required coordination across the police districts.

Canterbury Police conducted 137 prevention patrols targeting dishonesty offending and reducing harm on the road.

Forty-three arrest warrants were executed and 15 search warrants were conducted.


A significant amount of cannabis, cash, stolen cars and a grenade were amongst the items found by police during the warrants.

Others have been summonsed or warned for minor offending.
