TORONTO (AP) — Police said nine people are facing charges in what authorities are calling the biggest gold theft in Canadian history from Toronto’s Pearson International airport a year ago.

Peel Regional Police said Wednesday that 6,600 gold bars worth more than 20 million Canadian dollars ($14.5 million), and CA$2.5 million ($1.8 million) in foreign currencies were stolen. The gold was melted down and used to purchase illegal firearms, police said.

Those charged include an Air Canada warehouse employee and a former Air Canada manager who gave police a tour of cargo of the facility after the theft. A jewelry store owner is also charged.

“This story is a sensational one and which probably, we jokingly say, belongs in a Netflix series,” Peel Regional Chief Nishan Duraiappah said.

Peel Regional Detective Sgt. Mike Mavity said the gold bars, weighing 419 kilograms (923 pounds), and foreign currency, ordered from a refinery in Zurich, Switzerland, were transported in the haul of an Air Canada flight on April 17 last year.
