Thief walks away after €15m jewellery heist

A robber brandishing a pistol and a grenade stole diamonds worth 15 million euros ($16 million)  in Cannes and calmly escaped on foot, a regional prosecutor said.The man in his 30s, his face uncovered except for a pair of sunglasses, entered a luxury jewellery shop on the city’s famed Croisette waterfront promenade and initially passed himself off as a customer.“He asked to see diamond ornaments on behalf of a sponsor. The saleswoman was suspicious and gave him a catalogue,“ the prosecutor said.He then pulled out a 7.65-calibre automatic pistol and a grenade and ordered the two saleswomen to open the display cases, the prosecutor said. The investigators did not know whether the grenade was real.Nobody was injured during the hold-up, which lasted about eight minutes, a source close to the investigation said.
