Security forces were conducting sweeps at Ohio’s Wright-Patterson Air Force Base late Thursday after reports of an active shooter but within hours an "all-clear" was given, according to reports.
The all-clear was reported over the base's loudspeaker public address system more than four hours after two people reported hearing shots fired, according to FOX 8 in Cleveland.
The entire base was on lockdown, but emergency responders focused on the base’s National Air and Space Intelligence Center in Area A, according to a tweet from the 88th Air Base Wing.
The base’s loudspeaker could be heard from outside the base saying, "Lockdown, lockdown, lockdown," according to WHIO.com.
Wright-Patterson is Ohio’s largest single-site employer with more than 27,000 civilian employees and military personnel, The Associated Press reported.
