PHILADELPHIA (CBS) — Police say a 33-year-old woman was shot on a SEPTA platform in West Philadelphia Wednesday afternoon when a group of teens was chasing another group and one fired a gun. It happened just after 3 p.m. on a platform at the 46th Street Station on the Market Frankford Line.

Though the shooting happened at a SEPTA train station, Philadelphia police are leading the investigation. It appears the victim may have been an innocent bystander.

Officers rushed the woman to the hospital after she was shot three times in the stomach. She is currently in stable condition.

Police say a group of teenagers chased another group of teens into 46th Street Station, when one teen fired a gun from the mezzanine toward the top of the escalator, striking the woman multiple times.

Officials say the alleged shooter was taken into custody Wednesday night.

Philadelphia Police Staff Insp. Derrick Wood added the shooter “narrowly missed shooting a woman and a child when he fired into the crowd. His disregard for human life was appalling.”
