NORMAN, Ok. - UPDATE: University of Oklahoma officials say authorities have found no evidence of shots being fired on campus and no injuries have been reported.
The school had posted a notice on its website earlier Wednesday saying there had been reports of a shooting and that people should avoid Gould Hall, which is near the center of campus.
University spokeswoman Catherine Bishop says in a statement that normal campus operations have since resumed except for Gould Hall, where additional checking is continuing Wednesday. She says no evidence has been found of any shots being fired.
ORIGINAL STORY: A message was posted to the university's official twitter account telling students to avoid Gould Hall.
Norman police tell us officers are on the scene assisting campus police with a shots fired call at the campus that came in just after 11 a.m. They dispatched officers and medical personnel but could provide no other information.
Professor Mike Boettcher is in a classroom with students across from Gould Hall. He tells 2NEWS they're being asked to stay where they are.
Boettcher says about 15 cruisers from city and campus police pulled up from the south oval to Gould Hall. Officers emerged from their vehicles with guns drawn.
The student newspaper, The Oklahoma Daily, is reporting that Dale Hall is also being evacuated.
