A Philadelphia man acted in self-defense when he shot a 16-year-old who attempted to rob him using a fake gun, according to police. The incident occurred just after 11 p.m. Sunday in the city’s Kensington neighborhood, as reported by 6abc in Philadelphia.

The 16-year-old suspect, along with an accomplice, approached the 21-year-old man on the street and attempted to rob him by flashing what appeared to be a firearm. Unbeknownst to the teens, the victim was armed with a real 9 mm pistol and was also licensed to carry. In response to the threat, the man drew and fired his weapon, wounding the suspect in the leg as he turned to flee.

Philadelphia police say the shooting, which was caught on surveillance video, was a clear case of self-defense.
