An 11th-grader was in stable condition Friday after being shot at a Redondo Beach high school when a friend's handgun, carried in a backpack, accidentally discharged, authorities said.
The 12th-grade student who had taken the .38-caliber handgun to Redondo Union High School cooperated with police after they arrived on campus to investigate, school officials said.
He was arrested on suspicion of having a stolen firearm and of possessing a firearm on campus and was released to his parents. Police and school officials said neither student had a criminal record or a known gang affiliation.
The incident took place about 10 a.m. when about 75 students were in the freshman quad area at snack time. The senior set his backpack on a ledge, but it fell to the ground and the gun went off, officials said.
