HAYWARD -- Firefighters tackling a one-alarm house fire on Wednesday night discovered more than 200 marijuana plants inside the home, a Hayward fire official said.

The blaze broke out just before 7:30 p.m. at 23201 Lori Way in unincorporated Alameda County, said Hayward Fire Department Battalion Chief Scott Anderson.

When firefighters arrived at the 1,200-square-foot, four-bedroom home, they found an electrical meter arching outside the home's garage, Anderson said Thursday.

No one was home when the fire started no one was injured.

While fighting the blaze, crews found a marijuana grow inside the home's garage and alerted the Alameda County Sheriff's Office.

The cause of the fire was not immediately known but Anderson said it appears it may have been electrical.

Damage, he said, was contained to the meter and a wall where the meter was located.

It was not immediately known on Thursday if any arrests were made.

Anyone with information about the fire can call the Sheriff's Office at 510-667-3602 or an anonymous tip line: 510-667-3622.
