Campus police gave the all-clear at Oklahoma State University after investigating a report of shots fired at Edmon Low Library on Tuesday afternoon in Stillwater.
Students received an automated alert and were asked to stay away from the area about 11:15 a.m.
Monica Roberts, a spokeswoman for the university, said about 11:20 a.m. police secured the area and checked the building. About 12:45 p.m., police confirmed the reports of gunfire were unfounded.
Roberts said it’s possible the sounds could have been from construction work ongoing on the library’s fifth floor.
