Firefighters battled a suspicious fire at a seafood shop in St. Leonard late Saturday night.

The blaze began around 11:20 p.m. at United Seafood Packers Ltd., located on boulevard des Grandes-Prairies near boulevard Lacordaire.

The store had recently expanded to sell deli meats and specialty items, and the fire began in that section of the building.

Elements found at the store led firefighters to believe arson may have been involved.

Police are now looking to question a man who was seen near the store around the time of the fire.

The man is white, in his 20s, and roughly five-foot-six. He was wearing a green hoodie.

So far, no arrests have been made.
