Montreal police will spend the morning investigating a marijuana grow operation found in Roxboro.

Firefighters rushed to 4805 Lucerne St. in Roxboro at 4:30 Tuesday morning after flames were spotted coming from the home.

They promptly put out the fire but not before it caused major damage to the building.

While putting out the flames they discovered many marijuana plants growing inside the bungalow and so notified police.

Nobody was hurt in the fire.

Police have yet to make any arrests.
