LOS ANGELES (AP) —  Authorities have arrested a man on suspicion of starting a wildfire east of Los Angeles that has burned five homes and forced an entire town to evacuate.

State fire officials say 32-year-old Brandon N. McGlover of Temecula was arrested Wednesday on suspicion of setting at least five fires earlier that day in southwest Riverside County.

It's unclear whether he has an attorney.

The largest fire is a 7 ½-square mile (19-square kilometer) blaze in and around the San Bernardino National Forest that prompted mandatory evacuation orders for the entire town of Idyllwild and nearby communities. The fire remains out of control.

To the north, in the San Francisco Bay Area, at least one home burned in another fast-moving blaze in Clayton.

In the Sierra Nevada, famed Yosemite National Park was closed as smoke from a fire to the west cast a pall on the region.
