At approximately 4 p.m. on Monday afternoon, the fire was declared under control by DC Fire and EMS personnel.
The barricaded person was taken into custody and evaluated by paramedics. No other injuries were reported, and first responders were working to get residents back in the building after they were sheltered in a nearby recreation center.
