A boy was injured when his schoolmate brought a loaded gun to school Tuesday morning.

A 12-year-old boy brought a gun to school to show his friends at Glendale Intermediate School, 1430 Andrew Ave. About 9:45 a.m. a 14-year old boy took the gun, not realizing it was loaded and fired it. The bullet struck the floor and caused splinters that superficially injured the 14-year-old. He was treated at the school, Principal Rickie McCandless said.Salt Lake police Lt. Tom Brown said the gun was a chrome .22-caliber derringer.

The boy who brought the gun had transferred to the school three weeks ago. McCandless said the gun did not belong to member of the boy's family and didn't know where he obtained it. The principal said it was an isolated incident and she had never seen anything like it. The boy has been expelled pending review by the district superintendent.
