Fire rips through duplex

No injuries after a two alarm blaze tore through a duplex on the city's southside.  The inferno started just before 11:30 on Sherbrooke street and Thunder Bay Fire and Rescue Captain Rick Kerley says when crews arrived they saw blackened windows and smoke in the area. Kerley says they found extensive damage in the house but managed to confine most of the damage to the main floor.  There is no word on the cause at this time.
