Hamilton police have released security camera video of a stolen car being used as a battering ram to break into the Al Simmons Gun Store on Locke Street in an effort to find out who did it.

This hockey bag was left behind during a robbery at a Locke Street gun shop back in March, police say. (Hamilton Police)

It happened back in the early morning hours of March 2, when a grey compact sedan slammed into the front doors of Al Simmons Gun Shop, located on the southwest corner of Locke Street South and Canada Street.

Three men used the hole in the front of the building to get inside and grab several guns before running off, police say. Those guns were recovered not long after by police.

The suspects left behind a large black hockey bag with white trim that has a stitched on Pittsburg Penguins logo and the number nine on it.

Police are still looking for the suspects and are asking anyone with information to contact police at 905-546-2991 or Crime Stoppers at 1-800-222-TIPS.
