A 15-year-old Chatfield High student was hit while crossing the street at a crosswalk and police are asking for the public's help to find the car involved.

According to information from Colorado State Patrol, the student was crossing West Chatfield Avenue just south of Ken Caryl Avenue in Littleton around 2:45 p.m. when a blue/grayish newer model Toyota Prius plowed into him.

The Prius fled the scene and witnesses could only give scant details about the vehicle, CSP says.

The student is seriously injured and was taken to Littleton Hospital.

If you saw something - say something. The vehicle should have damage to its front and windshield.
