A suspect in a shooting at a Philadelphia high school that left two students wounded turned himself in Saturday, police said. According to local ABC affiliate WPVI-TV, the suspect is also a student.

Earlier on Saturday, police said they had issued a warrant for the suspect and expected him to turn himself in accompanied by an attorney. Another suspect turned himself in on Friday.

The shooting occurred in the school gym. Police told WPVI, surveillance footage showed the gun went off as it was being taken out of a bag.
