Italian authorities have arrested eight individuals believed to have been involved in hiding trillions of dollars of fake US bonds.
Worth $6trn, the bonds, which gave the appearance they had been issued by the US Federal Reserve in 1934, were found in three metal boxes in a warehouse in Zurich.
Prosecutors are not sure what the gang was planning, but think they intended to sell the counterfeit bonds, the BBC writes.
Investigators, based in Potenza in southern Italy, say the fraud posed "severe threats" to international financial security.
