REDDING, Calif. (AP) — A wildfire in Northern California that authorities say was sparked by exhaust from a truck is growing and threatening additional homes. State fire spokesman Daniel Berlant said Tuesday morning the Bully Fire around the rural community of Igo in Shasta County was threatening more than 50 homes, up from about 15 a day earlier. Some of those homes are under mandatory evacuation orders, although Berlant did not know exactly how many. The fire, which began Friday, has burned through 6,400 acres, or 10 square miles. It is 20 percent contained.
It has destroyed eight homes and ten other structures. Seven firefighters have suffered minor injuries. A Sacramento man has been arrested on suspicion of starting the blaze. Authorities say he was delivering material to a marijuana site when the exhaust from his truck ignited dry grass.
