An affiliate of Lloyds of London is offering €1m reward for information leading to a diamond collection stolen at gunpoint from a jewel show in Cannes.

A massive €102.5m in jewellery has been stolen from an exhibition at one of the French Riviera’s top hotels.

The massive €40m jewellery theft in Cannes happened at a hotel that featured prominently in Alfred Hitchcock’s “To Catch a Thief,” which starred Cary Grant as a reformed burglar chasing a jewel thief.
