The National Post reports in its Thursday edition that shock Toronto airport heist of $20-million in gold bars along with $2-million (U.S.) in cash was as easy as walking into Air Canada's cargo facility, showing a false waybill, and leaving with the enormous haul, according to a lawsuit. The Post's Adrian Humphreys writes that it was gone 42 minutes after it was unloaded from a plane arriving from Switzerland and transferred to a supposedly secure warehouse on the periphery of Toronto's Pearson airport, according to the statement of claim. The theft, one of the largest in Canadian history, remains unsolved. Brink's is now suing Air Canada over the lost loads. The lawsuit paints the clearest picture yet of how April's airport gold heist was allegedly pulled off after months of silence from police, the airline and others involved. In a statement of claim filed in Federal Court, Brink's claims Air Canada provided woeful security despite knowing the high-value contents. "Upon receipt of the Fraudulent Waybill, AC personnel released the Shipments to the unidentified individual," the lawsuit claims. "AC accepted the Fraudulent Waybill from the unidentified individual without verifying its authenticity in any way."
