Thieves smashed their way in and ripped out the functional toilet, hours after a glamorous launch party at the Oxfordshire stately home in September 2019.

Michael Jones was found guilty of planning the burglary. Fred Doe was convicted of conspiring to sell the gold, while Bora Guccuk was cleared of the same charge.

The BBC can now reveal the full criminal history of the heist gang's kingpin James Sheen. He has been jailed at least six times since 2005 and has led organised crime groups that made more than £5m from fraud and theft - money authorities have largely failed to recover.
