The University of Oklahoma now is reporting “no evidence” has been found of any shots being fired on its campus in Norman, Okla. No injuries have been reported either, it said.
The university had reported a shooting on its campus at about 11:30 a.m. Central time. It warned students on Twitter to avoid Gould Hall and seek immediate shelter in place.
Normal campus operations had resumed by about 12:10 p.m. in all buildings except Gould Hall. Officials were continuing to check the building, it said.
KJRH is reporting Oklahoma University President David Boren is telling students the sound of equipment backfiring likely was mistaken for shots being fired. That call had come from a faculty member, Boren later said. Students also may have reported the same.
The university has not completely ruled out gunshots, he said, but he reiterated it has found no evidence of gunshots.
The reports come one day after a gunman killed one person at Purdue University in Indiana.
