Philadelphia Police release video in hopes of identifying suspects.
Police are looking for a Sixers fan who got into an argument with a Bulls fan while on his was home from the game then opened fire hitting the Bulls fan and an innocent bystander.
Authorities tell NBC Chicago sister station NBC10 the shooting happened around 10:30 p.m. on the Market-Frankford Line at the 46th Street Station in West Philadelphia, just after the 76ers lost to the Bulls 96-89.
"It's bizarre. This is behavior that is just over the top," Lt. John Walker told the station. "It's intolerable. I mean, people have to realize this reckless behavior can not continue."
Police say the two men, both between 17 and 20 years old, were arguing about the game for quite some time before the suspect exited the the train at 46th Street, turned and fired one shot into the crowded subway train, striking the Bulls fan in the stomach. The bullet went through the man and hit an innocent bystander in the leg, according to officials.
Police tell NBC10 that the victim who was shot in the leg stayed on the train until the next stop. From there, he went to a relative's house and that relative called the authorities before taking him to the Hospital of the University of Pennsylvania where he was treated for a gunshot wound to the leg.
The Bulls fan was also taken to HUP.
Both victims are expected to make full recoveries.
The shooter ran from the subway and is still on the loose.
"Here's a young man, who obviously has anger management issues," said Lt. Walker. "Instead of just controlling his anger and dealing with the issure, he decides to fire a shot into a crowded train."
