Bernie Ecclestone is nursing minor injuries after muggers attacked the F1 chief executive and his girlfriend Fabiana Flosi outside his London home.
The Sun reports that the 80-year-old was rushed to hospital with a head injury after the four attackers punched and kicked him as they stole watches and jewellery at 10.30pm on Wednesday.
Photographs of the F1 chief executive returning to work on Thursday morning showed a red mark on his right hand.
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."
Earlier this month in Brazil, Ecclestone brushed off an attempted armed mugging or kidnapping involving F1's reigning world champion Jenson Button.
"They look for victims, they look for anyone who looks like a soft touch and not too bright," said the Briton in Sao Paulo.
"People who look a bit soft and simple, they will always have a go at."
