A 7-year-old boy alerted a teacher after finding a loaded gun in his backpack at an elementary school in Philadelphia, police said.
It happened during an after-school program at Universal Samuel Daroff Charter School in west Philadelphia around 4 p.m. Thursday. School officials told police the boy was putting a folder in his bag at the end of the day and noticed the gun.
The principal said staff immediately took the backpack and called police.
Lt. John Walker said police are interviewing the boy's family and reviewing surveillance video to figure out how the gun got into the bag.
Walker said it was a .38-caliber handgun loaded with five rounds of ammunition. The boy said he had his backpack with him in the classroom the entire day.
