The media report said two classmates at West Kearns Elementary School reported the gun to a teacher toward the end of the school day yesterday.
Granite School District spokesman Ben Horsley says the teacher “immediately apprehended the student,” and police responded shortly after.
Horsley tells KSL-TV that an unloaded gun and ammunition were found in the 11-year-old's backpack. Authorities have not released the child's name.
Horsley says school police are investigating reports that the boy pointed the gun at another child's head. He says such accounts haven't been confirmed.
Authorities say no one was injured.
