(Waupun) A detached garage in Waupun was damaged by fire Friday afternoon. Crews responded to 516 Grace Street around 11:18am for a report of a structure fire. Smoke and flames coming from the garage were visible upon arrival. Fire Chief B.J. DeMaa says firefighters forced entry into the garage through a service door and discovered a fire burning near the roof. He says crews initiated an interior fire attack and quickly knocked down the blaze before it extended to the nearby house. Damage was contained to the garage with initial damage estimates of $3,000 to $5,000. DeMaa says while the fire remains under investigation, lightening in the area is being looked at as a possible cause. No one was injured during the incident. Assisting the Waupun Fire Department was the Waupun Police Department and Lifestar Ambulance.
