Louisiana State University officials have given the all-clear after a report of an armed intruder on campus.

LSU spokesman Ernie Ballard says a shelter-in-place order is over and authorities have determined there was no threat. He says the university is returning to normal operations after police conducted a room-by-room search of Coates Hall and found no threat.

Ballard says LSU officials were aware of a plainclothes police officer who had a visible gun on his belt and was in the building for an event at the time of the report. But officials said they do not know if that's what prompted the report of a gun.
