As firefighters work to extinguish the Sandy Fire, police are investigating an incident that may have sparked the blaze.
Simi Valley police told Eyewitness News that someone called the department just before 10:30 a.m., saying they were clearing brush with a tractor when they struck a rock, which then ignited a fire.
The police department could not confirm if that incident is what started the fire, but police said it's a possibility.
