No active shooter at Joint Base Andrews

JOINT BASE ANDREWS, Md. (WTVD) -- Joint Base Andrews was put on lockdown due to a report of an active shooter Thursday morning and all personnel were directed to shelter in place.

Officials later said the report was unfounded. An employee at a medical facility at the base outside Washington said an active-shooter drill had been planned Thursday morning, but officials later told workers it was a "real-world" situation.

It later turned out that someone looking out a window saw the drill in progress and thought it was the real thing.

The Maryland base is the home of Air Force One and other military units.
