According to police, a 51-year-old man was riding a bike heading northbound on 202 when he was struck.

An older model silver sedan, possibly a Dodge Neon, was traveling in the right lane when it swerved toward the shoulder, striking the bicyclist.

"The vehicle then swerved back into the right lane and failed to stop, continuing to travel northbound on Route 202," Pa. State Police Sgt. James Hennigan told Action News.

A witness who was several car lengths behind stopped and called 911.

Police say the victim rode his bike to work each day from his home in Wilmington to Chadds Ford. The bicycle was properly illuminated with lights on the front and the back. However, the bicyclist was not wearing a helmet and suffered severe head trauma.

"Even though it was dark," said Hennigan, "the bike should have been visible by using those lights."

Police believe the striking vehicle may be an older model silver sedan - possibly a Dodge Neon. They're checking for surveillance video in hopes it helps track down the hit and run driver.

There was one camera near the scene, but police say it was not pointed in the direction of the incident.

The victim's name has not been released.
