Calgary police say staff at a convenience store found something strange while unpacking a shipment of pre-made food.
It's alleged that two clear, heat-sealed bags discovered in the shipment contained two kilograms of a substance believed to be heroin.
Investigators say the bags had the word "Navi" written on the outside.
Police say employees at the store in northeast Calgary were unpacking the shipment on March 11 and called police when they found the suspicious packages.
It's been determined that the food shipment originated from California but police are still trying to find out when the drugs were added and who they were meant for.
Police asking anyone with information to contact them.
