Thousands of people were under evacuation orders Friday and many others were on notice to be ready to flee as a destructive wildfire raged in a drought-stricken forest in California’s far north.

A woman suspected of starting the Fawn Fire was under arrest, authorities said.

The fire in the Mountain Gate area north of the city of Redding covered more than 9 square miles and was 10% contained, according to the California Department of Forestry and Fire Protection, or Cal Fire.

Co-workers Rajdeep Singh, 35, of Rocklin, Calif., and David Bailey, Jr., 29, of Sacramento, were arrested on multiple counts of insurance fraud and arson after allegedly conspiring to commit vehicular arson in order to receive an undeserved insurance payout of over $30,000.

The Sacramento Fire Department on June 24 responded to a vehicle fire in a parking lot and identified the vehicle as a 2016 Honda Pilot. The morning of the fire, the registered owner’s son, Singh, arrived on the scene and claimed the vehicle had been stolen while he was working at his job, Primetime Autos, a used car dealership where he worked as a finance manager.
