Two people have been arrested in connection with the massive industrial fire at the former Wickes Bumper Manufacturing site.

Police have arrested a 16-year-old and 18-year-old.

Both suspects are charged with arson causing damage to property. 

The 16-year-old has been released on a promise to appear in court.

Police said they expect to release the 18-year-old today with a promise to appear in court.

Police declined to say how they tracked down the two suspects.

The fire caused $1 million in damage. Windsor Fire and Rescue say it was deliberately set.

Police were investigating it as an arson.

The former chrome-plating plant was acquired by the City of Windsor in lieu of back taxes in 2009.

The City had trouble selling the building due to potential contaminants including chromium, copper and nickel that were left behind when the factory closed in 1990. 

Lee Tome, the city's chief fire prevention officer, said none of those were still present inside the building.  

Police continue to investigate.
