The bomb squad was called in after Strathcona County RCMP pulled over a car in Sherwood Park with a mismatching plate, only to find weapons and an improvised explosive device inside.

The discovery happened Tuesday afternoon, around 1:30 p.m. Mounties were patrolling in Sherwood Park, checking licence plates in a parking lot off Pembina Road and Broadmoor Boulevard.

Police ran the plate of a Buick Verano and said it was not a match to the car and also was not supposed to be attached to a registered motor vehicle.

A traffic stop was initiated, during which police spotted bear mace inside the Buick, whose driver was allegedly attempting to conceal something down the side of the driver’s seat, which was later determined to be a knife.
