Scotland Yard has charged eight suspects with conspiracy to burgle in the well-planned Easter weekend break-in at a safe-deposit box facility in London's famed diamond district.

Police say a ninth man has been freed on bail but is still facing questions.

The group is accused of climbing down an elevator shaft and drilling through thick concrete walls to gain access to the vaults.

The eight men who have been charged, aged between 48 and 76, are set to appear in court Thursday.
