The American University campus, located in northwestern Washington, D.C., ended a lockdown Wednesday after several reports of an "armed intruder" near the college. The campus is on lockdown as police respond to the incident and search campus buildings.
According to a university statement, campus police ordered a lockdown out of an abundance of caution after receiving a report of a man in the 3300 block of New Mexico Avenue with an exposed handgun at approximately 1:11 p.m.
No shots were fired, an American University spokeswoman said, and the school instructed students, faculty and staff on campus to shelter in place.
The investigation is focused on Main Campus, East Campus and 3201 New Mexico where a building by building search is underway. "I'm not necessarily going to be checking AU's alerts and checking their Twitter page every single day to make sure my life isn't threatened". All other locations remain on lockdown, they say.
Officials say those who are outside should leave campus immediately.
American University says e-mail alerts have been delayed due to a technical issue and has been resolved.
American University student newspaper The Eagle reports that some students have not received alerts despite the correction.
