CHICAGO – Two bystanders were shot, including a 13-year-old boy, Friday afternoon on Chicago’s South Side.

Police say the shooting occurred near 79th and Ashland in front of a Shell gas station.  Authorities are reviewing security footage and attempting to locate the gunman.

The 13-year-old boy, who is expected to survive, was shot in the neck while sitting on a CTA bus. First responders took him to Comer Children's Hospital, where he had surgery.

A 28-year-old man was also wounded and taken to the hospital.  He suffered a gunshot wound to the ankle but is OK.

Police say the incident began with a fight between two people inside the gas station. When the two walked outside, a third person followed them and began shooting.

The bus was stopped at the corner when the shots were fired.
