Firefighters responding to a call for electrical fire in the garage of a Roseville neighborhood on Thursday discovered what might be a part of an extensive marijuana growing operation. The Roseville Fire department was reported of the small fire coming from the electrical panel on the side of the house by neighbors who thought the house was unoccupied.

According to police, fire crews presented the need to go inside the house as part of routine check for such fires, and as they entered the house they found sophisticated marijuana growing system, including lighting, irrigation lines, timers and a bypassed electrical system which apparently caught fire.

"This is unusual for us," Sgt. Ned Rosenbrook, Roseville Police spokesperson told the Roseville Press Tribune adding that police have seized all the equipment and hundreds of the plants of the psychoactive herb.

The news comes nearly a week after police arrested three people for allegedly running an indoor marijuana-growing operation in nearby Elk Grove neighborhood in Sacramento, Stockton.
