THUNDER BAY -- Billowing black smoke and flames came through the roof of a John Street house after a fire broke out Saturday evening.
Thunder Bay Fire Rescue crews were called to a blaze on the 900 block of John Street, where thick smoke filled the neighbourhood.
Platoon Chief Craig Venables said all four occupants were able to escape the residence and nobody was injured.
Firefighters battled the fire from the rear of the building, which saw flames visible through the roof of half of the duplex.
Venables said the fire is believed to have started outside the residence and engulfed the rear and main floor were fully engulfed.
The fire was contained to the one half of the duplex, Venables added.
Five pumpers and an aerial ladder, along with multiple ambulances, responded to the call.
An inspector is on scene and investigating possible causes.
