SOUTH FORSYTH -- The Georgia Arson Control Board is offering a reward for a two-alarm fire that destroyed a house and outbuilding at 5520 Old Atlanta Road Wednesday night.

Forsyth County Fire Department Division Chief Jason Shivers said the house and outbuilding, which were apparently abandoned, were both burning when firefighters arrived at about 1:30 a.m.

The walls of the brick home are still standing, but the interior is reportedly gutted. The outbuilding, which was likely either some type of barn or shop, according to Shivers, was destroyed.

Shivers said that both buildings are a total loss and that one firefighter was injured when he stepped off a deck that was failing and broke an ankle.

A total of six engines and one truck responded to the fire, along with two battalion chiefs and three investigators, Shivers said.

Shivers said an investigation is still underway but that the fires have already been ruled arson.

Anyone with information can call the Georgia arson control hotline at (800) 282-5804.
