Police had previously said yesterday's theft at the Carlton Intercontinental Hotel had netted USD 53 million in loot -- even at that level one of biggest jewelry heists in recent years.
Assistant prosecutor Philippe Vique said the Dubai-based organiser of the diamond show has raised the value based on a more complete inventory.
Vique said authorities are looking for a lone suspect who broke in through French doors at the hotel that opens out onto Cannes' famed Croisette. The suspect then fled on foot.
