PHILADELPHIA (WPVI) -- Philadelphia police are investigating after a teenager was shot near the basketball courts in Center City Philadelphia.
It happened around 6:54 p.m. Friday on the 2500 block of Delancey Place at the Schuylkill River Park.
Police say the victim was shot once in the arm. He was taken to an area hospital in stable condition.
"We just heard bang, bang, bang. We just ran," said Yosef Nisimi who lives nearby.
Nisimi and Maurice Kanter say they ran for their lives Friday evening when they heard about 12 gunshots.
"We didn't know what to do. They had to go back and grab their phones off the bench and run. Our ball is still right out there on the court. We just ran," said Kanter.
Detectives believe teenagers were playing basketball when other teens fired a gun from a nearby ramp. Police say those on the court returned fire and everyone started to run.
No additional injuries were reported.
Officers arrested three males and recovered four guns not too far from the scene.
"You don't really see this type of stuff in the neighborhood. We've been coming here for a while and this never happened," said Kanter.
Police are still trying to determine what led up to the shooting, how many people were involved, and if there are any more suspects.
Anyone with information is asked to call police at 215-686-TIPS.
