Two teenage boys were wounded in a shooting in Frankford Monday night, police said.

The victims, both 17, were sitting on a front stoop on Ditman Street near Scattergood at 10:35 p.m. when they were shot, Chief Inspector Scott Small said. One suffered a through-and-through wound to the left foot and the other was grazed in the underarm, Small said.

Both were taken to Aria Health's Torresdale hospital and listed in stable condition.

The boys told police they did not know who shot them, investigators said, but described the shooter as a 16 or 17-year-old boy who is thin and wore a black shirt. He was last seen running north on Ditman. Police said the teens told them they don't know why they were shot, so cops are unsure what motivated the crime.

Small said the door of the house the boys were in front of was struck by gunfire and the siding on the house next door was damaged by three bullets. Cops found two projectiles at the scene, including one that fell out of the sock of the victim who was shot in the foot when medics tended to him at the scene.

Police remained at the scene investigating shortly after 11 p.m.
