The Windsor Police Service is searching for leads in a suspected arson along Tecumseh Rd. E, between Central Ave. and the Windsor Assembly Plant.
Officers discovered a building on fire Monday while out on patrol. The bottom half of the structure is a business, while the top is an apartment.
Police say no one was inside any of the units which were on fire.
An investigation later determined that the blaze was intentionally set.
