Sheboygan Firefighters were called to a fire on the north side of the city late last night. A call came in just before 11:30 PM reporting visible smoke emitting from the home on the 1500 block of Michigan Ave. Upon arrival, crews saw black smoke coming from the second floor. They quickly located and extinguished the fire. No injuries were reported, as the occupants had safely evacuated by the time crews arrived. The cause remains under investigation.
