PEORIA, Ariz. -- Investigators say a fire at a Peoria strip mall now is an arson case and three gasoline cans found at the scene are being treated as evidence.
Authorities say the fire was reported about 11 p.m. Tuesday and it took more than 20 units from six cities to extinguish the blaze.
They say the fire started at a beauty college that wasn't equipped with sprinklers.
The building was gutted by the fire and two surrounding businesses sustained heavy smoke damage.
No injuries were reported, but investigators quickly classified the fire as suspicious and say the gasoline canisters were left in the parking lot.
Phoenix TV station KTVK reports federal authorities were at the scene Wednesday to assist in the investigation.
