Suburban police are hoping a photo will help lead to a suspect wanted in two carjackings.
Police say an armed man carjacked a vehicle in Orland Park on October 18.
They say he was speeding westbound on 159th Street into Oak Forest, where he crashed and struck a construction worker.
Investigators then say he stole a second vehicle and struck a police officer who was chasing him.
Anyone with information should call police in Orland Park or Oak Forest.
