Police are searching for a driver of a white or silver vehicle involved in a hit-and-run accident near 52nd and Spruce that left a bicyclist critically injured. Police say that the crash happened at around 2:20 a.m. on Tuesday. The victim, a 46-year-old man, was thrown off his bike after the impact with the vehicle and sustained head and body injuries. He was listed in critical but stable condition at the hospital where he was rushed after the incident. The vehicle that struck the man never stopped, according to police.

Police say there were no witnesses to this crash. They’re currently reviewing surveillance videos from the area.

This is the second hit-and-run accident involving bicyclists in West Philadelphia in the past month. Last month, a 27-year-old man died from his injuries after a hit-and-run crash near 45th and Market. The driver who struck him still hasn’t been found.

On Wednesday, May 18, the Bicycle Coalition of Greater Philadelphia is organizing a Ride of Silence to commemorate Philadelphia-area cyclists killed in collisions with motor vehicles.
