The Mountain Home Air Force Base says false reports of shots fired caused a lockdown early this morning.
The lockdown was put in place around 4 a.m. after an active shooter incident was reported.
Security forces investigated and discovered reports of shots fired were false. The lockdown was lifted around 6 a.m.
The report of shots fired came from what somebody heard during a training exercise. Officials at the base say somebody misinterpreted that as a "real world event".
The base announced yesterday the 366th Fighter Wing would be conducting 24-hour training today through Friday to prepare for real world contingencies. That notice also said Mountain Home residents might hear increased noise during the training.
