Calgary police are hoping someone recognizes a man who robbed two stores and attempted a third with a weapon between Friday and Saturday mornings.

The suspect — between 25 and 30 years of age, roughly six feet tall with a medium build and shaved head — tried to rob the Hampton's Co-op Liquor Store Friday morning using a weapon but he wasn't successful and fled on foot.

He then entered a liquor store on Edgedale Dr. N.W. and got away with cash and liquor at about 11 a.m., police say.

Police believe the same man hit the Subway restaurant at 11300 Tuscany Blvd. N.W. Saturday morning, fleeing on foot after getting cash.
