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.
