DALTON TOWNSHIP, Mich. -- The Dalton Township Fire Department says the Michigan State Police and the Bureau of Alcohol, Tobacco, Firearms & Explosives (A.T.F.) are now investigating Wednesday's big fire at a Muskegon County gun/ammunition shop, south of Twin Lake.
The Michigan State Police Rockford Post tells FOX 17 the MSP Fire Division has yet to determine the cause of the fire, and damage estimates have not been calculated.
The fire was reported at about 5:30 p.m. Wednesday at Grasmeyer Bros. LLC, 4786 Holton Rd.
Twelve fire departments responded to the scene. Roads were closed in the area for a short time. Firefighters who fought the fire faced discharging ammunition.
Smoke was visible for miles as crews worked to contain the fire. No injuries were reported.
The Dalton Township Fire Department says officials were called to the shop at about 3 p.m. Wednesday for a fire involving a work bench. That fire was contained before crews were called back for the larger blaze.
It's unclear if the two fires are related and the cause remains under investigation.
