An elderly man is accused of bringing a gun to a Thatcher, Arizona, school because he was upset with the "loud music."
Around 11:34 p.m. Friday, officers were called to Thatcher High School where 150 students were attending a school dance in the parking lot, police said.
Officers say 72-year-old Robert Layton went to the school with a gun and was waving it around. At some point, Layton allegedly assaulted a school employee and a DJ playing music at the dance helped detain him until officers arrived.
Authorities located a 9mm handgun on Layton, officials said.
Layton told officers he was upset about the loud music and wanted to shut it down, police said.
He was taken to the hospital with minor injuries suffered during the altercation. Afterward, he will be booked into Graham County Jail.
