Authorities in northern Arizona say someone intentionally set a series of small fires that forced the evacuations of about 50 homes in a rural subdivision near the mountain town of Flagstaff.
Coconino National Forest spokesman Brady Smith says a combination of up to nine fires sprang up at about the same time Wednesday afternoon about eight miles northeast of Flagstaff.
The Coconino County Sheriff's Office says they're looking for a man who witnesses saw near the fires at around the time they started.
Smith says the fires were 20 percent contained at less than 100 acres by 7:30 p.m. Evacuees were expected to be allowed to return home by late Wednesday night.
The fires are unrelated to the massive wildfire burning about 200 miles away in eastern Arizona.
