Winnipeg police said a fire that broke out in a vacant business on Main Street Tuesday was deliberately set.

Crews were called just after 11 a.m. about heavy smoke pouring out of the building at 1051 Main.

It took about 45 minutes to put out the fire, and there were no injuries.

There is no damage estimate available yet.

Traffic on northbound Main in the area continues to be reduced to a single lane as crews clean up the scene.

Arson investigators are looking into the cause of the blaze.
