OAKLAND -- A house heavily damaged by a fire last year in East Oakland that was being rebuilt was destroyed by a blaze Thursday night that officials have deemed suspicious.

The house, at the corner of 84th Avenue and Dowling Street only had its framing up and no siding at all, said Battalion Fire Chief Emon Usher.

He said neighbors reported hearing an explosion just before the fire erupted at 8:01 p.m. and when they went to look saw the entire structure on fire.

It took 24 firefighters until 9:35 p.m. to control the flames. There were no injuries.

Usher said heat from the fire caused some windows to break at an adjacent apartment building. The fire also burned some power lines that fell to the pavement, causing a small power outage to residents in the area that was quickly restored by PG&E workers, Usher said.

He said no one claiming ownership of the property showed up at the scene.

Usher estimated damage to the structure to be at least $100,000 and said the exact cause is still under investigation.
