Dozens escape burning party bus in Norwalk

NORWALK, Calif.

The bus was forced to pull over on the 10000 block of East Imperial Highway.

Police say about 40 people onboard were traveling back to Compton from a Pasadena movie theater when they smelled a suspicious odor or smoke. That's when the driver exited the freeway and pulled into a doughnut shop parking lot where the engine caught fire.

Investigators say a mechanical failure caused the fire.

No injuries were reported.
