Davis-Monthan Air Force Base in Arizona was locked down for a period Friday due to a potential security situation, but an investigation revealed no shots were fired and nobody was injured, according to a report.
A spokesperson at the base said partial lockdown was ordered after a report of suspicious activity. Several emergency vehicles were seen heading to the base, about five miles from Tucson. The Associated Press reported Friday afternoon that traffic into and out of the base is limited but no shots have been fired.
The base is near the Pima Air & Space Museum, and is a popular destination for old military and government airplane aficionados.
A Tucson Police Department dispatcher who didn't want to be identified told NBC News that they received a 911 call from soneone on the base reporting that shots were fired and that one person may have been injured. The dispatcher reported to NBC News that the call was from a person who claimed to be a sergeant.
