LA VERNE -- A fire that burned some 95 acres near a golf course in La Verne has been ruled arson.

The fire broke out just before 4:00 p.m. Sunday, forcing the evacuation and closure of the Marshall Canyon Golf Course.

About 200 firefighters worked to extinguish the blaze, which was fully contained by 8:00 p.m., said Captain Mike Brown of the Los Angeles County Fire Department.

Authorities say the fire was ruled arson because there were two points of origin.

"Basically, there were two spot fires with vegetation between the two, and it was off a dirt road," Brown said.

Firefighters were able to to stop the flames from spreading to three nearby homes, said Captain Brown.

No injuries were reported.

The cause of the fire is under investigation.
