Dirksen Courthouse Locked Down After Knife Threat

The Everett McKinley Dirksen United States Courthouse in downtown Chicago was placed on lockdown Tuesday morning after reports of an armed individual, possibly with a knife, in the building's lobby who reportedly threatened self-harm. The FBI, SWAT, and Chicago police responded, deploying negotiators to the scene. Authorities instructed people inside to remain in place and avoid the lobby, while access to neighboring federal buildings was also restricted. The incident caused major traffic disruptions in the Loop due to road closures. No injuries or arrests have been reported, and officials have not disclosed information on the suspect or motive. The investigation is ongoing, and the public has been advised to avoid the area.
