The Cincinnati Enquirer reports he'll be charged in juvenile court with inducing panic for taking the BB gun to his elementary school Monday in suburban Elmwood Place.
Officer Leah Schindler says a principal reported Monday that a handful of students saw the weapon. Schindler says the children believed the gun was more powerful than a BB gun, and one said the boy threatened to fire it.
Schindler says the boy reported getting the gun from his mother.
The newspaper says the boy's mother didn't respond to an interview request, and school officials couldn't be reached for comment.
