A vacant house under renovation was set on fire early Monday morning a few blocks from downtown Macon.
Firefighters, called to the blaze about 4:20 a.m., found flames shooting through the roof of the wood-frame house at 1266 Third St., which is between Ash and Hazel streets.
An arson investigator, Sgt. Ben Gleaton, ruled it an incendiary fire and posted reward signs at the house before the sun came up.
Authorities are investigating another blaze that happened a few months ago at the house next door.
Yellow tape used to block off that fire scene was still crumpled around on the ground.
Anyone with information on Mondays arson is urged to call the hot line at (800) 282-5804.
Tipsters can remain anonymous and could be eligible for up to $10,000 in reward money.
