OAKLAND — Fire crews have extinguished a blaze Friday afternoon at a two-story Victorian house in East Oakland that authorities believe was started by a marijuana grow.

Crews responded to the 1700 block of 10th Avenue about 1:30 p.m. and controlled the fire at 2:06 p.m., officials said.

No one was injured.

Firefighters found large banks of batteries in an attic, which appeared to be powering equipment for the pot grow.

It was not immediately known if the grow was legal.

Battalion Chief Melinda Drayton said there were marijuana plants in one room of the three-bedroom home. Damage to the structure was estimated at $100,000. A damage estimate for the contents was not immediately known, Drayton said. The owner of the home, who does not live there, was at the house, but was not available for comment.
