(CNN) — The University of Oklahoma in Norman briefly shut down Wednesday after a report of a possible shooting.
No evidence has been found of any shots being fired, and no injuries are reported, school spokeswoman Catherine Bishop said.
After telling students to shelter in place for more than 30 minutes, the school announced that normal campus operations had resumed — except at Gould Hall, the site of the reported shooting, “where additional checking is continuing,” the school tweeted.
Gould Hall houses the university’s College of Architecture.
University and campus police responded quickly, as did emergency personnel, the school tweeted, adding that the school’s president, David Boren, is at the scene.
Maj. Bruce Chan of campus police told CNN there was a report of shots fired in that area of campus. It was not immediately known whether anyone has been wounded.
The incident took place at around 11:20 a.m. local time (12:20 p.m. ET), while classes were in session.
Students and faculty were alerted via text.
On Tuesday, a gunman shot and killed a man at Purdue University in Indiana.
