Crews from Tucson Fire Department battled a two alarm fire that destroyed a two-story building in midtown Tucson Saturday night. 

Crews were dispatched to the building in the 3900 block of East Fort Lowell Road around 10:30 p.m. after witnesses called 911 and reported seeing heavy smoke coming for a building behind a salon and spa, Capt. Barrett Baker, a Tucson fire spokesman said in a news release. 

When crews arrived flames were visible from outside the building and heavy smoke was coming from the vents and eaves of the building, indicating the fire was coming from the attic space.

A ladder crew cut a large ventilation hole in the roof and popped through two sky lights. Onlookers said flames were shooting more than ten feet high after the holes were cut, the release said. 

Crews fought the fire from the outside and an aerial poured thousands of gallons of water into the holes to put out most of the flames. 

When most of the flames were extinguished firefighters used extension ladders to get into the attic space and put out hot spots, the release said. 

Nobody was injured in the fire. 

More than 40 firefighters helped battle the blaze. 

The fire started when wood material placed in the fireplace earlier that day was moved outside and placed up against the building, the release said. 

"The wood burned under the frame stucco wall and into the void space around the fireplace," the release said.
