CBS News said that US Marshals confirmed that a man with a knife tried to get past the security at the building around 11 a.m. local time but was stopped by the security officials in attendance.

It sparked a huge police response at the scene, with the FBI, SWAT, Chicago police, and some agents from the Department of Homeland Security at the scene of the incident.

No one was injured in the incident; Chicago police confirmed the CBS.

However, the active investigation resulted in multiple road closures near the courthouse, causing heavy traffic.

Locals have been asked to avoid the area as the FBI probe continues.
