Fire investigators are looking for the cause of a massive blaze in Nanaimo last night.

The fire broke out in the Acme building on Commercial Street around 6:30.

Karen Lindsay with the fire department says it was a tricky fire to battle. She says the wind played a major factor, and shifted the direction of the smoke, making the process to put it out that much more difficult.

Lindsay says that fortunately no one was hurt. Investigators are on scene today looking for the cause of the blaze.
