Canada police have made arrests and issued warrants for nine people in what is considered the largest gold theft in Canadian history.
More than 6,500 gold bars, weighing roughly 400kg (881lb), were stolen from a cargo facility at Toronto Pearson Airport, in April 2023, along with millions in cash.
The stolen gold was valued at C$20 million.
Police said the "Netflix-series"-style heist was executed by a "well-organized group of criminals".
The investigation is ongoing.
The announcement Wednesday by the Canadian Peel Regional Police and the US Alcohol, Tobacco and Firearms Bureau came exactly one year after the massive gold heist, reportedly the sixth largest in the world.
The year-long investigation by US and Canada law enforcement, largely secret until Wednesday, was code-named Project 24K. It included dozens of search warrants and interviews.
So far, police have recovered C$90,000 worth of "pure gold" fashioned into six "crudely made" bracelets. They also seized smelting pots, casts and moulds, as well as C$430,000 in cash that police say is part of the profits the suspect made when they sold the gold".
On Wednesday, police also emphasized they found 65 guns after arresting one of the suspects.
In September, Pennsylvania police arrested an Ontario man illegally in the US, and he was identified as the driver in the heist, police said.
Police stopped him in Philadelphia for a traffic violation and discovered firearms in his car. He is still in custody. Five other suspects were arrested and released pending a court appearance; three arrest warrants have been issued for others in Canada.
"One of those firearms had an obliterated serial number, 11 of them were stolen, and two of them were converted into fully automatic machine guns," Eric Degree, a special agent of the ATF in Philadelphia.
According to police, those guns were "intended for import into Canada". "This isnt just about a gold heist, this is about how gold becomes guns," said Nando Iannicca, chair of the Peel Police Services Board.
Police said the guns seized in the US were a "dotted line" to peoples wellbeing in Canada.
The 17 April 2023 heist occurred inside a cargo holding facility, after it arrived on an Air Canada flight from Zurich, Switzerland. Police allege that an unidentified person was able to access the goods by showing a fake airway bill - a document that accompanies shipped items.
A five-tonne truck was then used to steal with the goods, police said.
Months after the theft, Brinks International, a US-based security company due to coordinate the shipment of the goods, sued Air Canada.
Brinks alleged that the airline had been "reckless" and had failed to prevent the theft, making no attempt to verify the identity of the person who "absconded with the cargo". According to the lawsuit, the goods were stolen 42 minutes after they were unloaded from the plane.
"No security protocols or features were in place to monitor, restrict or otherwise regulate the unidentified individuals access to the facilities," Brinks claimed.
Air Canada has denied "each and every allegation" made by Brinks, rejecting any accusations of "careless" conduct. The airport has claimed the thieves "accessed the public side of a warehouse that is leased to a third party, outside of our primary security line".
Brinks is suing for damages liability, and has asked that the value of the goods stolen be paid back by the airline in full.
