LOS ANGELES (CBSLA) — A greater alarm fire ripped through an auto parts storage facility in Cypress Park early Tuesday morning.

More than 100 firefighters were called in to battle the blaze, which was being fueled by dense interior storage, according to Los Angeles Fire Department spokesman Brian Humphrey.

Firefighters were able to keep the fire to within the building, but the fire was not yet fully extinguished as of 6:15 a.m., according to Humphrey. San Fernando Road was closed to traffic to allow for firefighter operations.

LAFD officials say fire was officially declared out at 10:41 a.m., but firefighters were forced to remain at the scene into the afternoon and beyond to ensure no hot spots would allow the fire to spark back up.
