Police are searching for a driver who hit a 4-year-old boy and ran off in Chicago's West Ridge neighborhood on Sunday night. 

Around 9:40 p.m., Chicago police said the 4-year-old was walking with a 24-year-old man in a crosswalk, in the 2700 Block of West Peterson Avenue, just across Washtenaw Avenue from Green Briar Park, when they were hit by the gray car.

The driver got out of his car and fled the scene on foot, police said. 

Police say the man and boy were taken to local hospitals, where they were listed in fair condition. 

No arrests have been made.

The area of Peterson Avenue where the hit-and-run happened is part of a major through-route between the Edens Expressway and DuSable Lake Shore Drive.

Area Three detectives are investigating.
