FRENCH investigators have found jewels valued at $25 million hidden in a Paris rain sewer - part of the spectacular 2008 heist from luxury jeweller Harry Winstons Paris boutique. Nineteen rings and three sets of earrings - one pair valued at $19.5 million - were dug up from a drain at a house in the working class Paris suburb of Seine-Saint-Denis, police said, confirming a report on Europe-1 radio. The jewels were hidden in a plastic container set in a cement mold inside the sewer, police said. The bold Harry Winston robbery on Dec 5, 2008, netted the thieves gems and bejewelled watches worth up to $118.1m, police said. Agencies
