OAKLAND — Seven people were displaced Thursday morning after a fire at an East Oakland apartment complex, officials said.

No one was injured but a dog perished in the apartment where the fire started.

The fire started about 10:48 a.m. Thursday at a four-plex in the 7800 block of Ney Avenue. When firefighters first arrived bright orange flames were visible inside one apartment.

The fire apparently ignited in the kitchen of one apartment and spread to an adjacent unit and through the roof, officials said.

The fire, which sent smoke 100 feet into the air, was brought under control in about 45 minutes by 20 firefighters, Battalion Fire Chief Tracey Chin said.

The seven residents of the complex, including a child, were able to get out on their own. They were being aided by the Red Cross.

Chin said the apartment where the fire started was heavily damaged and the other one sustained mostly smoke damage. She estimated damage to be at least $180,000.
