The active shooting reported on Thursday that led to the lockdown of Maryland's Joint Base Andrews was a “miscommunication,” according to U.S. military officials.
Joint Base Andrews officials said a “no notice” shooter exercise was scheduled to take place in the late morning on the opposite side of the base outside Washington.
Military officials confirmed there was “no threat to base” and the active shooter was mistakenly reported after someone saw security forces making a routine inspection.
“Fortunately, this was not a life-threatening situation. We take all threats seriously and reacted to ensure the security of those on the base. I applaud the quick reaction of our first responders in keeping the safety of our JBA family a number one priority,” U.S. Joint Base Andrews Commander Col. Brad Hoagland said in a Tweet.
The lockdown was lifted more than an hour after the first response. No shots were fired and no one was hurt.
During the lockdown officials had posted messages on Twitter and directed all personnel to shelter in place.
“The base was scheduled to conduct an active shooter exercise, however, reports of a real-world active shooter situation were reported at Malcolm Grow medical facility,” officials shared online before they declared the "all clear."
According to reports, Vice President Joe Biden was scheduled to leave Thursday morning from Andrews to Columbus, Ohio, for a campaign event with Gov. Ted Strickland. His departure was delayed.
Joint Base Andrews is the home of the president's aircraft, Air Force One, and other units. The base is in Prince George's County, Maryland, east of the U.S. capitol city.
