CHICAGO (CBS)– One person was seriously injured in a shooting early Friday on the Dan Ryan Expressway.

Illinois State Police said at least two vehicles were heading south on I-94 near 63rd Street around 12:40 a.m., when the people inside the cars began exchanging gunfire, before exiting the expressway.

Troopers responded to a report of a vehicle damaged in the shooting, and were later informed by Chicago Police of a shooting victim who was being treated at a local hospital with serious injuries.
