INGLEWOOD, Calif. — A noninjury fire that appears to have been set by one or more transients to keep warm broke out today at a vacant house in Inglewood, authorities said.

The first firefighters to reach the single story house at 4020 West Century Blvd. at 12:18 a.m. reported it was “fully involved in flames,” said Los Angeles County Fire Department Dispatch Supervisor Andre Gougis.

Firefighters had the flames knocked down in five minutes, he said.

Gougis said it was evident that a warming fire had quickly gotten out of control. He said whoever started the fire was gone by the time firefighters arrived.
