LA PRESA, Calif. -- A motorist who fled on foot after a two-car crash in the South Bay is behind bars Monday on suspicion of drunken driving, authorities said.

The crash on Jamacha Boulevard, just west of Sweetwater Road, was reported at 10:36 p.m. Sunday, according to the California Highway Patrol.

Witnesses helped officers track down a man who ran from the scene, the CHP reported. His name was not immediately released.

There were no serious injuries, a Heartland fire dispatcher said.
