Authorities took into custody a man suspected of carrying a gun onto Middle Georgia College's main campus Monday, the Bleckley County Sheriff's Office said.

The man, who was not identified, was not a student at the school in Cochran, located about 120 miles south of Atlanta, college officials said.

Earlier Monday morning, the college was placed under a lockdown after a student reported seeing a man with a gun. Authorities conducted a room-by-room search of the college.

The college has resumed normal operations and the lockdown was lifted around noon, said college president Mary Ellen Wilson.

The sheriff's office said there were no reports of shots fired.

Georgia law prohibits carrying guns on college campuses.
