Video captured multiple police cars pursuing a Honda heading westbound on I-88. Eventually, the chase stopped, and officers got out of their cars with guns in hand.
The DeKalb Fire Department said the shooting happened near Keslinger Road in the Maple Park area.
The person struck by gunfire was transported to a hospital, the fire department said. Their condition was not immediately known.
Chopper 7 managed to get a shot of what appears to be a gun laying on the road next to the vehicle.
ABC7 cameras captured a broken passenger's side window, but it is unclear how that window was damaged.
All westbound lanes were shut down for hours. They began reopening around 7:30 p.m.
Officials did not immediately provide further information.
