Teen hit by two cars left on road

The moment a teenage girl was hit by two cars and both drivers fled the scene has been caught on camera outside a US college.

The unidentified 14-year-old high school student was hit with a glancing blow before being knocked down by a second car while running through moving traffic in Santa Ana, California, on Monday.

Both cars, a red pick-up truck and black sedan, fled the scene but a good Samaritan chased one of the drivers in his car while calling 911.

The 32-year-old driver of the red pick-up was caught and charged with hit-and-run.

Police are still hunting for the driver of the black sedan, who witnesses say stopped briefly after the accident before leaving the scene.

"I can't explain it," Santa Ana police officer Weston Hadley told CBS.

"[The driver was] there for some period of time. They just never identified themselves to any law enforcement personnel … and left the scene."

The teen was uninjured in the collision.
