A child admitted playing with a lighter under a bed in a home on East Tennessee Avenue when a mattress fire was found at about 7:04 p.m. Monday, an Oak Ridge Fire Department report said.
Firefighters reported light smoke inside the house when they arrived, and they quickly found a smoldering mattress fire in a bedroom inside, the report said.
They reported the fire was under control, ventilated the home, and removed the mattress and box frame.
