Norridge Detective Sgt. Brian Loughran said the officer’s quick thinking may have saved his life.

The officers are searching for the attacker.

After police recovered an abandoned vehicle in the 4000 block of Marmora Avenue, Loughran said they are seeking a 40-year-old Chicago man.

The attack occurred between 9:40 and 9:50 p.m. on Wednesday.

Driven by a 42-year-old Chicago woman, the 47-year-old man was in the passenger seat of the vehicle. The woman informed police that she had been driving behind the attacker and that he “kept hitting his brakes,” She was able to get around the car and pass it, telling police that the other driver then started to tailgate her.

The woman told police she was stopped at the stoplight at Harlem Avenue across when she saw the other driver get out of his car and approach her vehicle. She then drove off, traveling north on Harlem Avenue. The man then returned to his car and again, was tailgating her, and then she pulled into the BP lot, police said.

At BP, the other driver got out of his vehicle – first walking to the driver’s side of the woman’s car. The 47-year-old man then got out of the passenger’s side of the women’s car and was confronted, police said.

The 47-year-old man at the hospital told police that he threw a punch in an attempt to distract the other driver, feeling threatened after seeing a knife in the man’s hand. The man was then attacked, stabbed in the arm, leg, and stomach before the other man drove away.

Witnesses said they were able to provide the fleeing vehicle’s license plate information.

The woman told police they “have no idea who the offender is, never met him, don’t know of him.”

Norridge Police Officers Anita Sasiadek and David Drwal were able to assist the 47-year-old man, using a tourniquet to stop the bleeding on the man’s arm as well as perform CPR – as the man lost consciousness and stopped breathing due to the wounds at one point.
