Rupert Murdoch was pelted with a white substance during his appearance before MPs today.
Mr Murdoch's young wife Wendi and his son James jumped to his defence as the attack was launched as the final questions were being asked by MPs.
The hearing was suspended as a man wearing a checked shirt with what appeared to be foam splashed across his face was detained by police.
Mr Murdoch, 80, was apparently pelted with a plate of foam.
MP Chris Bryant condemned the attack in which he said the media mogul had the plate pushed into his face.
