TORONTO (AP) — Police have made arrests in the theft of a cargo container that included gold and other items worth over 20 million Canadian dollars ($14.5 million) that were stolen from Toronto’s Pearson International airport a year ago, authorities said Tuesday.

Peel Regional Police and the U.S. Alcohol, Tobacco and Firearms Bureau will announce details and arrests at a new conference about the case on Wednesday.

Police said last April that a “high value” container was taken from a holding area facility after being unloaded off a plane. The missing goods were reported to police a short time after that. Police declined to provide more details at the time.

Brinks, an American cash handling company, later sued Air Canada over the theft. According to the company’s filing last year, a thief walked away with the costly cargo after presenting a fake document at an Air Canada warehouse on April 17.
