CHICAGO (WLS) -- Two pedestrians injured in the Belmont Cragin neighborhood after a suspect's car went out of control.
Chicago police detectives are investigating a crash that sent one of their own officers to the hospital and injured two elderly bystanders who, police say, were standing on the sidewalk waiting for a bus.
Just after 11:30 a.m., police say officers in an unmarked police vehicle tried to pull a car over on the Northwest Side. Investigators say the car initially stopped and then drove off.
As officers in the unmarked car followed the alleged suspect's vehicle, it collided with another marked Chicago Police cruiser that was responding to an unrelated call.
