Jeweller to the royal household hit by smash and grab raiders - leaving one man covered in blood

A jeweller to the royal household was today targeted by smash and grab raiders in a violent attack - leaving one man covered in blood.

William & Son in London's exclusive Mayfair district was targeted by thieves reportedly carrying metal baseball bats.

Images on Twitter show a man with blood pouring from his head as a metal baseball bat lies on the pavement beneath the door to the shop, in Mount Street.

The luxury jewellery and riflemaker supplies goldsmith and silversmith services to the royal household.

The shop confirmed there had been a smash and grab raid this afternoon.

But they declined to comment on the details, including what, if anything, was taken and if anyone was injured, because a police investigation has been launched.
