The search of a Glace Bay landmark destroyed by fire Friday continues. 

Cape Breton Regional Police Staff Sgt. Ken O'Neill says they have information that a homeless person could have been in the building at the time of the fire.

However, O'Neill says investigators have searched about 75 per cent of the scene and haven't found any sign of human remains.  

He says investigators are now focusing their search on the basement of the structure. 

There's still no word on what caused the fire.

Fire crews were called to a major structure fire at the Billy D's/Guildwood building on Main Street around 11 p.m. Friday. Glace Bay Fire Chief John Chant says it was fresh footprints in the snow that led authorities to believe someone could have been inside.

Chant says 70 to 80 firefighters from more than a dozen fire departments responded to the blaze.
