Police say a large quantity — but not all — of the 400 kilograms of nearly pure bullion bars stolen in the Toronto airport gold heist was melted and transformed in a workshop in the basement of a local jewelry store.

Smelting equipment used to turn molten gold into long, thin strips, and another machine that can twist and shape metal into bracelets were found by police inside the basement forge that included an oxy-acetylene torch, crucibles, metal tongs, and moulds.
