RAF Mildenhall in England was on lockdown for about an hour and a half Tuesday in response to reports of an active shooter that turned out to be inaccurate.
A base exercise was happening when the alarm was sounded at 1:18 p.m. Emergency personnel responded and determined that there was no shooter.
An announcement posted on the base Facebook page at 2:46 p.m. said the lockdown was implemented after officials determined that the reports of the active shooter were unrelated to the exercise.
No service members or families were injured during the lockdown, according to the statement.
“Today we are thankful for the quick reaction of our airmen, who are highly trained and ready to respond to any situation,” Col. Gene Jacobus, the 100th Air Refueling Wing commander, said in the statement
