"Chicago Fire" was forced to stop production after shots were fired nearby where the NBC show was filming Wednesday, the Chicago Police Department confirmed to Fox News Digital.
Authorities responded to the scene shortly after 1:45 p.m. when an "unknown offender, armed with a handgun shot at a group of people standing in the 5900 block of W. Madison Street" near the Oak Park area of the city.
While "no one was struck," the suspect fled the scene in a "dark color SUV" and detectives are investigating the shooting.
