The Calgary Police Service has released footage of a July robbery near a downtown office tower as officers attempt to identify the three people responsible for the attack that left one man stabbed, pepper sprayed, beaten and robbed.

According to police, at approximately 9:30 p.m. on Tuesday July 15, 2017, a man in his late 20s was in the courtyard east of Aquitaine Tower, in the 500 block of 5 Avenue Southwest, when he was attacked by three men.

The suspects stole the man’s backpack before stabbing, beating and pepper spraying the victim. The injured man fled the area, made his way to a nearby restaurant, Poco Loco Pizza, for help and he was subsequently transported to hospital. The robbery victim has since recovered from his injuries.
