A scary situation Monday night around 10 o'clock at the High River 7-11.

Police say a man wearing a white mask came into the store and threatened the clerk with a knife, demanding money.

Before the clerk could respond a customer in the store shoved the man into the door causing him to take off running.

No money was taken and no one was hurt.

However Mounties believe the man was working with two other men.

The suspect is described as in his mid-twenties, 6' to 6'1", wearing light blue jeans, white running shoes, and a flourescent orange construction jacket with a reflective "X."

Anyone with information is asked to call the High River RCMP at (403) 652-2357 or Crime Stoppers at 1-800-222-8477 (TIPS), or by Internet at www.tipsubmit.com.
