Up to three boys may have been involved in the shooting of a couple of fellow students inside a high school in Philadelphia, police said.
One boy was captured near his home but has been released from custody and is no longer a suspect.
A second boy turned himself in. The search continues for a third involved party.
The gunfire erupted shortly before 3:30 p.m. Friday inside the Delaware Valley Charter School at 5201 Old York Rd. in the Logan section of north Philadelphia.
Approximately seven students were in the gym hanging out and playing basketball when one of the students pulled out a gun, and the gun, either intentionally or accidentally, went off, said Commissioner Charles Ramsey, Philadelphia Police Dept.
Two students -- a boy and a girl who are approximately 15-years-old -- were each hit by the gunfire, police said.
The victims were rushed to Einstein Hospital, about a block away from the school. One victim has been released from the hospital. The other is still in the hospital in stable condition.
The school was immediately placed on lock down while SWAT officers worked to make sure the building was secure. They then proceeded to dismiss students one by one.
Parents of students at the school were asked by police to report to Fisher Avenue and Old York Road and not to go to the school.
