Police say an expensive necklace was stolen overnight in the luxurious resort town of Cap d'Antibes, the second jewelry theft on the French Riviera during the Cannes Film Festival.

A police official said Thursday that the necklace was of "high value" but couldn't put a price on it. She would only speak on condition of anonymity because an investigation is under way.

Last week, thieves stole about $1 million worth of jewels after ripping a safe from the wall of a hotel room in Cannes, where the world's movie stars are attending the festival.

Cap d'Antibes is just down the coast from Cannes and, if possible, even more exclusive.
