UPDATE: Reports of an ‘armed intruder’ stirred up concern on LSU’s campus Tuesday afternoon.

The alert went out around 3 p.m. warning students to stay away from Coates Hall. It included a message telling people to “run, hide or fight,” a saying used by many universities nationwide during potentially dangerous situations on campus.

A witness who was inside the building said a member of the cleaning crew said they thought they saw someone with a gun and staff reported it to police. An LSU spokesperson says the scare may have been caused by a police officer in plain clothes walking around with a gun on his belt.

Police have found no threat on campus. No injuries were reported.
