There was no real world active shooter incident on Wright-Patterson AFB and base personnel remain safe.— Wright-Patterson AFB (@WrightPattAFB) August 2, 2018
Reports of the active shooter also began with a tweet from the base telling workers at Wright-Patterson were told to shelter in place.
At approximately 12:40 p.m., base emergency responders (security forces, fire department) responded to a reported Active Shooter incident at the base hospital.— Wright-Patterson AFB (@WrightPattAFB) August 2, 2018
Base personnel have been directed to shelter in place until the incident is investigated
Video from outside of the hospital showed service members and others standing outside the building.
WHIO-TV reported that an all-clear was given to base personnel shortly before 3:00 p.m., advising the threat has passed.
Our first priority in any emergency incident is to protect the men and women at Wright-Patt. Our base security forces defenders and fire department personnel are trained to quickly assess situations and take necessary action. An investigation is under way.— Wright-Patterson AFB (@WrightPattAFB) August 2, 2018
The call came during a training exercise that included an active shooter scenario in another area of the base at least a half-mile away, said Daryl Mayer, a base spokesman.
So far, it's not clear why the 911 call was made from inside the base or whether it was prompted by the training exercise, he said.
Security team members involved in the training don't fire blanks and use guns that clearly aren't real, Mayer said.
Local police were directing traffic away from the base, which is Ohio's largest single-site employer with more than 27,000 civilian employees and military personnel.
The base's commander, Col. Thomas Sherman, said security forces stopped their training exercise and responded to the hospital after the 911 call. After security searched the hospital, which had been on lockdown, they determined there had been no active shooter.
"I wouldn't say anything went wrong in this case," Sherman said, adding that there will be an investigation into the entire response.
The Ohio State Highway Patrol and local police also had officers at the base.
The base was the site where the Dayton Peace Accords were finalized in 1995, an international peace agreement that ended the war in Bosnia.
