JOINT BASE ANDREWS, Md. — Joint Base Andrews tweeted Thursday that the base was on lockdown due to a report of an active shooter and that first responders are now on scene to secure the base.
The base has instructed all personnel at the base in Washington’s Maryland suburbs to continue to shelter in place and stay inside.
Later tweets from the base said the incident was ongoing at the Malcolm Grow Medical Facility and first responders were on the scene. The account instructed everyone to continue to shelter in place, a precaution meant to keep people safe while remaining indoors.
It also clarified earlier reports that a drill was scheduled for the day on how to deal with active shooter situations, saying a drill was in fact scheduled, but reports of a “real-world active shooter situation” then emerged.
Joint Base Andrews is located about 20 miles outside of downtown Washington, D.C. and hosts aircraft used by President Obama.
Rodney Smith, the patient advocate at the Andrews medical facility, said an active-shooter exercise was scheduled for Thursday morning, and then he was told it was a “real-world” situation. He said he was on lockdown and didn’t have any more information.
“First it was an active-shooter exercise. Then it came back ‘real world,'” Smith said by phone Thursday morning.
Smith said the situation was unfolding at the newer of two buildings at the Malcolm Grow Medical Facility on the base. He was in the older building.
