Authorities said the Wednesday night confrontation on the Market-Frankford line was sparked by a dispute over the 76ers' loss to the Chicago Bulls earlier in the night.
Lt. John Walker said a Bulls fan quarreled with the two young men before being shot in the stomach. A second man who tried to calm things down was shot in the leg. Both victims were taken to a hospital for treatment and are expected to survive.
In the video, the faces of the two suspects are clearly shown. People on the train platform at 46th Street in West Philadelphia scatter after the shooter fires his handgun into the stopped train car.
Police asked the public's help in identifying the suspects.
