The Department of Homeland Security said in a statement, “On the morning of October 20, an FPS Protective Security Officer reported an active shooter on Federal property near the John C. Kluczynski Federal Building in Chicago, IL. FPS personnel and the Chicago Police Department responded. Local police took the subject into custody. There were no injuries reported, only minor damage to federal property. As this is an active and ongoing investigation, additional information will be limited until concluded.”
Chicago police said a male suspect was taken into custody, a gun was recovered from the scene and charges are pending.
A spokesperson for the U.S. District Court for the Northern District of Illinois said there is no active threat and the Dirksen Federal Courthouse remains open.
All morning, police canvassed the area for evidence, at one point appearing to focus on this ramp.
The plaza is home to several federal offices, including the Post Office, the Dirksen Courthouse, the Kluczynski Federal Building, and the General Services Administration.
Authorities confirming those sites sustained only minor damage.
Across the street, at least two bullet holes in the side of this office building just above the busy sidewalk below.
