SAN DIEGO (CBS 8) - Investigators are trying to determine the cause of a van fire in Clairemont that spread to another car and a telephone pole before it was put out.

Firefighters were called to the 4300 block of Bannock Avenue just before 11 a.m. Neighbors say some parked the van in a back alley area on Monday before it caught fire Tuesday morning.

Witnesses used garden hoses to try to put the fire out before emergency crews arrived.
