PHOENIX - Maricopa County Sheriff's officials say they've discovered a marijuana grow house in New River, north of Phoenix.
Daisy Mountain fire officials were initially called to the home Thursday morning after a fire started in the bedroom of the house.
The fire eventually moved to the attic.
Nobody was inside the home at the time of the fire.
Phoenix TV station KTVK says authorities are working to determine whether the grow operation is legal or not.
