BERKELEY -- Fire crews quickly extinguished a two-alarm fire in downtown Berkeley on Friday afternoon.

The fire broke out about 2:24 p.m. Friday at a building at the corner of Shattuck Avenue and Blake Street, a fire official said.

No one was injured. Nearly three dozen firefighters helped bring the blaze under control by 2:54 p.m., a fire official said.

A barber shop is on the bottom floor of the building and there are at least eight apartment units above the shop. A damage estimate was not immediately known and the cause of the fire is under investigation.

Berkeley Fire Department spokesman Avery Webb said the fire is believed to have started between two buildings.

At least eight people displaced from their homes will be assisted by the American Red Cross, Webb said.

The fire was originally a three-alarm fire but the third alarm was called off, Webb said.
