Oakland police spokesman Roland Holmgren said that the plants, as well as various cultivating paraphernalia, were found inside the house by Oakland firefighters responding to the structure fire on Moraga Avenue.
"That's what caused the fire," Holmgren said. "Nine times out of 10 we stumble on these grows because of some sort of electrical fire."
The Oakland Fire Department got a call about a single-alarm fire at 8:04 a.m., and extinguished the fire at 8:31 a.m., according to a fire dispatcher. Once inside the house, they found the plants and paraphernalia and alerted Oakland police.
Two men were arrested, with one having to be treated for smoke inhalation, according to a fire dispatcher.
Holmgren said that the names of the suspects would not be released until further investigation had been completed.
