New Delhi: The Andrews Air force base in Washington was locked down on Thursday morning due to report of an active shooter. The incident was going on at the Malcolm Grow Medical Facility. The base, located nearby in suburban Maryland, tweeted shortly after 9 a.m. that all personnel should shelter in place as it worked to provide more information.
 
The shooter was barricaded on the third floor of the medical centre, according to a reporter for the military newspaper Stars and Stripes.
 
“JBA is currently on lockdown due to a report of an active shooter. All personnel are directed to shelter in place. More info as it comes,” the base tweeted.
 
 
“The incident is ongoing at the Malcolm Grow Medical Facility. First responders are on-scene now. All personnel continue to shelter in place,” read another tweet.
 
There appeared to be some confusion whether the situation was real or part of a scheduled exercise. Base officials said the call came during an exercise but the report was real.
 
“We are reacting to a report of a real-world active shooter,” a spokesperson for the base told WTTG TV. 
 
“The call occurred during an exercise. Because the report came in as a real active shooter, we have to respond accordingly. We are treating as if it is and no further information at this time.”
 
The Joint Base Andrews is located around 20 miles outside of downtown Washington, D.C. and hosts aircraft used by American President Barrack Obama.
