Jewellery thieves strikes again on French Riviera NICE, France (Reuters) - Robbers stole 40,000 euros' ($53,000) worth of jewellery from safes in guests' rooms at a luxury hotel on the French Riviera, police on Saturday, continuing a string of heists on the Cote d'Azur. Two safes were raided at the five-star Grand Hotel in Saint-Jean-Cap-Ferrat and the robbers tried others without success, police said. Identity papers were also stolen. Last weekend, an armed robber stole jewellery worth $136 million (102 million euros) from a hotel in Cannes, in France's largest gem heist. In May, thieves hit the Cannes film festival, where many movie stars are lent gowns and gems to parade on the red carpets.
