Calgary police are looking for several suspects after a couple was robbed at gunpoint at a car wash late at night.

The couple first discovered that their vehicle had been broken into as they were eating dinner Wednesday night in the 3400 block of 17th Avenue southwest, police say.

Shortly past midnight, they drove the damaged vehicle to a nearby car wash to use a vacuum to clean up the broken glass.

At the car wash, they were confronted by five to seven black men, one of whom had a gun, police say. Police have not been able to provide a better description of the suspects.

The couple was forced to the ground and the man was struck on the back of the head.

The culprits stole a wallet, purse, phones and other items from the victims, police say.

The culprits left in a silver mini-van and a mid-size black car.
