An armed man held up a jewellery exhibition in the French Riviera resort of Cannes on Sunday, making away with jewels estimated to be worth about 40 million euros (USD 53 million), according to investigators.
Authorities said the hold-up took place in broad daylight at the Carlton Hotel on the promenade in Cannes, famous for its annual film festival that attracts a glittering array of celebrities.
Hotel management contacted by AFP declined to comment.
During the film festival in May, thieves stole jewellery worth USD 1.4 million that was due to be loaned to movie stars from a local hotel in a pre-dawn heist.
That robbery took place in the hotel room of an American woman employee of Swiss jeweller Chopard while she was out for the evening, police said.
A strongbox containing jewels was ripped out of the wardrobe and carried off, they said.
