A University of Georgia bus driver was arrested last week after leaving his handgun in a residence hall restroom, according to UGA police.

Brett Michael Davis, 30, stopped at Brumby Hall to use the men's room on the morning of Dec. 6, according to the Athens Banner-Herald. He took his gun out of his holster and placed it on the railing of a handicapped stall, then left without the gun.

Fifteen minutes later, he returned for the loaded weapon, but an administrator at the dorm had already seen it and called police, who were on the scene when he returned.

Davis, who has a concealed carry permit, was charged with bringing a gun onto school property and reckless conduct, both misdemeanors.

The campus carry law that took effect in July allows concealed-carry permit holders to bring guns onto some parts of campus, but includes an exception for dorms, where guns remain banned. Davis told police that he thought the nine-story building was a dining hall.
