"This was a very real event": Ohio's Wright-Patterson Air Force Base goes into lockdown for several hours after reports of active shooter on the base

Ohio's Wright-Patterson Air Force Base went into lockdown for several hours while security officials investigated reports of a shooter on the campus, but they eventually gave the all-clear early Friday morning.

Two individuals reported hearing one gunshot at the base just east of Dayton just after 9 p.m. Thursday, said Col. Patrick Miller, the Installation Commander at Wright-Patterson AFB. The report initiated a series of events leading to the lockdown. Over the next four hours, officials from the 88th Airbase Wing said, responders conducted two sweeps of the National Air and Space Intelligence Center, a three-story, 850,000-square-foot headquarters for the center described as the Department of Defense's primary source for foreign air and space threat analysis.
