Edmonton police are on the hunt for a man using a stolen gun to rob unsuspecting drivers across the city.

Investigators say, on Saturday Oct. 22, the suspect stole a firearm from a sporting goods store near 153rd Avenue and 37th Street.

Around 11 p.m. the same day, the suspect approached a stranger on the street near 162nd Avenue and 134th Street and asked for a ride. The suspect pulled out a gun and demanded money before fleeing the scene with an undisclosed amount of cash.

The next evening, police said, a taxi driver picked up a customer from the area of 38th Avenue and 91st Street and drove him to the area of 134th Street and 162nd Avenue.

When they arrived, the suspect robbed the driver at gunpoint and fled on foot.

At 9:30 a.m. the following morning, Oct. 24, another taxi driver was targeted by the same man.

Police said the driver was robbed of cash at gunpoint after he picked up a customer at a restaurant near 128th Street and 161st Avenue and drove him to the area of 133rd Street and 164th Avenue.

Investigators believe the same suspect is involved in all four crimes. They have released surveillance images in an attempt to identify him. Anyone with information is asked to contact EPS North Division or Crime Stoppers.

The suspect, believed to be in his mid-20s, is described as a black male with short black hair and dark eyes.

He is considered armed and dangerous and should not be approached.
