It happened late Thursday evening in the 6900 block of Aberdeen Road.
Police say a 21-year-old man was shot in the stomach during an attempted robbery. He was taken to the Hospital of the University of Pennsylvania in critical condition.
The victim was with a friend, police say, who told them two men approached them - one had silver handgun, the other had a double-barrel shotgun.
The men demanded money, and there was a brief struggle.
