Authorities have tightened the dragnet around the Louvre thieves, arresting five more people in connection with the recent crown-jewels heist. The Paris prosecutor says three of the four alleged members of the "commando" team are now in custody. The late-night operations in Paris and nearby areas have increased the total number of arrests to seven. Despite the arrests, the stolen loot, valued at around $102 million, remains missing. The heist, which took place in broad daylight, has sparked a national reckoning over how France protects its treasures. Security gaps at the Louvre have been acknowledged.
