PARIS — Cannes has been struck by its third high-profile jewelry heist in three months.

An armed robber made off with 40 million euros, or $53 million at current exchange, in jewels from the Carlton hotel on the Boulevard de la Croisette on Sunday morning, local media reported.

The circumstances of the theft were not clear, but the gems were reportedly destined for a temporary exhibition being held at the hotel.

Police officials could not be reached for comment. A receptionist at the Carlton hotel declined comment.

Jewel thieves struck twice during the Cannes film festival in May, making off with $1 million worth of Chopard jewelry and a De Grisogono necklace valued at 2 million euros, or $2.6 million.
