A gunman shot and critically injured a security guard at the U.S. Census Bureau headquarters in a suburb of Washington, D.C. on Thursday. Hours after the first reports of the shooting, the Bureau of Alcohol, Tobacco, Firearms and Explosives described the scene as an “active shooter incident.” There are reports that the gunman is barricaded at the building.
The security guard, shot in the chest, is in critical condition, according to local officials. “At about 7:45 p.m., roughly two dozen military-clad officers with rifles entered the Census campus and began sweeping through parking garages and lots,” according to the Washington Post.
