Detectives are hunting a “lone wolf” burglar who stole bespoke jewellery and designer items worth more than £10m in a 19-minute heist at a billionaire’s row mansion in London.

The man broke in through a second-floor window and cracked a safe to carry out what is believed to be one of the biggest ever thefts from a British home.
