The pint-size billionaire, 80, was rushed to hospital with a head injury after the ambush - on his doorstep.Four robbers were lying in wait at 10.30pm as he and new love Fabiana Flosi, 31, arrived at the F1 tycoon's central London HQ, where he has a spectacular eighth-floor penthouse overlooking Hyde Park.
Terrified lawyer Fabiana - who is also a sports marketing agent and model - watched helplessly as her mega-rich boyfriend was battered. Both were ordered to remove watches and jewellery.
Cops raced to the Knightsbridge HQ of the tycoon's business empire Formula One Holdings but the gang had fled with the loot.
Mr Ecclestone was taken to hospital where he was treated for what was described as a "minor" injury. Hours later he was defiantly back at work.
A red mark was visible on his right hand as his chauffeur dropped him at a meeting yesterday.
Fabiana was described as having been left "shaken".
Scotland Yard's Robbery Squad was last night hunting the muggers, whose haul included diamond rings. The same gang is feared to be behind a string of attacks on the rich and famous.
A senior police source said: "There can be little doubt this was a targeted robbery because of who Mr Ecclestone is.
The muggers were callous and showed little regard for the victims. They need to be caught."
Mr Ecclestone last year divorced his wife Slavica, 53. The couple have two grown-up daughters. As well as his penthouse and a string of properties around the world he has kept the family's £10million mansion in Chelsea Square.
Four years ago thieves swooped after he parked a brand new Mercedes-Benz CLS55 AMG outside. The car - said to be the first in Britain - had two of its wheels nicked.
