There has been another suspicious fire in the north end of Saint John.
This time it was at 131 Victoria Street, a large boarded up and vacant three storey wooden building.
The blaze was called in at 12:19 am and Platoon Chief Barry Oickle says it started in the back corner and went straight up to the roof.
One firefighter received minor injuries after a fall but was back on the scene a short time later after being checked at the hospital.
Oickle it will be determined later today if the building needs to be torn down.
