GREEN BAY, Wis. (WBAY) - Green Bay firefighters were called to an apartment building on Brosig Street Thursday night for a smell of smoke. But when firefighters arrived, they found little to no smoke. What they did find was a fire hiding inside the walls.
The call came shortly after 9 p.m. to the 1200-block of Brosig St. on the city's east side.
Firefighters used a thermal imaging camera to find the source of the smell and found a fire burning in the interior walls and insulation.
They tore out drywall from the walls and ceilings to put out the fire and tore out the insulation to make sure it wouldn't reignite.
The fire was contained to one apartment, but there was slight damage to another apartment in the effort to put the fire out, the fire department said.
Four tenants are getting help from the American Red Cross.
Firefighters don't know yet how the fire started. The department's fire marshals are investigating.
Damage is estimated at $40,000.
