A scrap of genetic material on a discarded painting cover allowed French investigators to track down two stolen Renoirs and to uncover what they suspected were preparations for a further art heist, a prosecutor said on Monday.
Nicolas Bessone, the Marseille prosecutor, said four men had been given preliminary charges over the theft from the small Renoir Museum in Cagnes-sur-Mer, a town on the French Riviera, on September 8.
