Nine warrants have been issued and an alleged gun-runner was arrested in the US carrying dozens of guns, believed to be intended for use in the heist.

The investigation is ongoing, with police describing the theft as an intricately planned crime by a well-organized group.

The announcement was made one year after the incident, which is reportedly the sixth largest gold heist globally.

Project 24K was a year-long joint investigation leading to the seizure of C$520,000 in gold, cash, and related materials.

Six "crudely made" gold bracelets and smelting equipment were recovered.

In September, an Ontario man, Durante King-McClean, 25, was arrested in the US with C$430,000 in cash and firearms, including two converted machine guns and an obliterated serial number gun.

Police suspect him of being the gang's driver.

Police have reported that a large shipment of guns intended for import into Canada was seized in the US.

Nando Iannicca, chair of the Peel Police Services Board, stated that this incident goes beyond a gold heist and is linked to the safety of Canadians.

The man involved in the case is currently in custody in the US on firearms trafficking charges.

The guns were described as a connection to potential threats in Canada.
