A driver has been arrested after authorities say he deliberately ran down and killed a jogger in a Los Angeles suburb.

Authorities say the jogger was in a bike lane in the city of Walnut shortly before 6 a.m. Monday when a Toyota Camry struck him from behind.

Authorities say the jogger was carried several yards on the hood of the car before the Camry went off the road and smashed through the brick wall of a backyard. The jogger died at the scene. His name hasn't been released.

Los Angeles County sheriff's Lt. David Buckner says it appears the driver intentionally struck the jogger although they didn't know each other.

The driver was arrested on suspicion of murder but his name hasn't been released.
