FREMONT -- Police are asking the public for help in locating a driver who collided with a bicyclist last month.

The crash took place just before 9:55 p.m. Sept. 25 at the intersection of Paseo Padre Parkway and Washington Boulevard, police spokeswoman Geneva Bosques said Thursday.

Witnesses at the scene dialed 911 and told dispatchers that a female bicyclist was hit by a car in the crosswalk of southbound Paseo Padre and that the driver of the vehicle did not stop.

When officers arrived they found an unconscious 20-year-old woman laying in the middle of the crosswalk with her badly damaged bicycle, Bosques said. The victim eventually regained consciousness and was transported to a trauma center with nonlife-threatening injuries and was released shortly thereafter.

Police said the bicyclist collided with the driver's side of the vehicle at either the front or rear tire area. The vehicle is described as black, possibly a four-door sedan.

Lead investigating Officer Kelly Snow said that "the driver may not even be aware of collision."

Anyone with information about the crash is asked to email Snow at Ksnow@fremont.gov or call 510-790-6760. Tips can also be left at www.fremontpolice.org/tip.
