WASHINGTON (WUSA9) — A lockdown of American University's campus began after a person on a university bus saw someone with a holster and called it in, a Metropolitan Police spokesperson said.

Police later determined the man was an off-duty police officer and the lockdown was lifted, Lt. Jesse Porter told the Associated Press. Porter said no weapon was ever displayed, no threats were made, no crime was committed and there were no arrests or injuries.

American Universiy's web site carried an alert at 9:25 p.m. ET that said, "ALL CLEAR. Campus is all clear, the lockdown is lifted. Campus may resume normal operations. Suspect in custody."

The report of the gunman came in to Washington police about 7:40 p.m. Wednesday, D.C. police spokesman. Officer Hugh Carew told the AP and officers searched the campus before the lockdown was lifted at 9:25 p.m..

American University and D.C. police were investigating near Gray Hall on Nebraska Ave.
