OAKLAND -- A home that was built before the 1906 San Francisco earthquake was scorched Wednesday in a two-alarm blaze that took fire crews three hours to get under control.
The fire broke out about 5:21 p.m. at the three-story, all wood-frame home on the 600 block of Harrison Street, just north of Interstate 880, said Oakland Fire Battalion Chief Melinda Drayton.
Drayton said the owner of the abandoned home believed squatters may have been to blame for the blaze, but Drayton said the cause of the fire is still under investigation.
When the roughly 50-strong crew of firefighters got on scene late Wednesday afternoon, not only did they set to work trying to put out the flames, they also had to rescue three people who were standing on the roof of the home next door, Drayton said.
Crews rescued the three people, whose identities have not been released, and they were immediately detained for questioning by police.
It is unknown if there were any arrests in regards to the fire.
As crews worked to put out the fire, traffic was blocked at Harrison and 7th streets, and commute times were also heavily delayed through the Posey Tube.
No one was injured as a result of the fire, and crews set up a night watch to make sure no one attempted to go into the home.
The home was built in 1896, authorities said.
