A 49 year old male CTA bus driver was driving when he heard a loud noise. The driver stopped the bus to inspect the vehicle. While inspecting the vehicle, the victim was approached by an unidentified male and female offender who began to push the driver. The two offenders then punched the victim multiple times before fleeing. The victim sustained bruises to the body and face and was transported to Northwestern where he is listed in fair condition. There is no one in custody and Area Three detectives are investigating.
