Arizona Student, 7-Years-Old, Fires Gun On Packed School Bus (VIDEO)

7-Year-Old Says He Got Gun From Home: MyFoxPHOENIX.com

An unidentified 7-year-old from Mesa, Ariz., has been detained after a handgun he brought discharged on a loaded school bus, authorities say, according to KSAZ TV. About 30 students were on board.

The report states that no one was injured on the bus from the Franklin Elementary School, and that the discharged bullet was lodged in the floor or a seat of the school bus.

Mesa Unified School District spokeswoman Helen Hollands told the East Valley Tribune that no one knew the student had the gun in his backpack, and that it fired a single shot after the boy "manipulated" it in his backpack.

According to a report by KPNX, police and school officials said the weapon was a .22-caliber pistol.

Parent Mike Place told KSAZ TV he's grateful nobody was hurt.

"I think it's a miracle for a handgun to be fired in close proximity on a bus and not have any of those students grazed, much less hit," he told the station, "It's a miracle and a blessing thank God none of them were hurt."

The station reports that the boy acquired the weapon from a closet at home and had the gun with him all day at school.
