WASHINGTON — A “shelter-in-place” order was issued at the Navy Yard here after “several” people reportedly were shot Monday at the Naval Sea Systems Command headquarters, the Navy said.

Washington’s Metropolitan Police Department reported that five people were shot and that a suspect was on the loose in the building. The shooter was described as a black male with a dark complexion, approximately 5’10” to 6 feet tall, 170 pound with a black shirt and black hat. He is believed to be barricaded somewhere and have multiple guns.

The Navy released a statement saying only that one injury injury was confirmed, but later said on its Twitter feed that “several’ people were injured. The Navy said earlier tweeted that there was an “active shooter” at building 197 at the Navy Yard, and that three shots had been fired at 8:20 a.m. ET.

District of Columbia Fire EMS units were on the scene. Officials said a medic unit, ambulance, and an engine company are responding as well as some EMS supervisors.

The headquarters is the workplace for about 3,000 people.

The sea systems command is responsible for engineering, building, buying and maintaining ships, submarines and combat systems for the fleet. The sea systems command is the largest of the Navy’s five system commands, with an annual budget of nearly $30 billion.
