Gatpandan said the bicyclist was bleeding when emergency crews arrived and that the four-door sedan involved in the collision remained at the scene.

KCBS’ Margie Shafer arrived at the scene of the cyclist accident and spoke to a witness who said they saw a 4-door white Honda Civic was headed north on Folsom and ran a red light as the cyclist turned left onto Folsom.

The cyclist, an older gentleman with gray hair, was said to be wearing a helmet. His glasses remained at the scene.
