Someone just accosted Rupert Murdoch during his testimony before Parliament, apparently in an attempt to throw a pie in his face. He doesn't appear to have been injured. His wife Wendi played bodyguard, catapulting herself toward the attacker with arms and nails flailing. His son James just stood there.
Update: The culprit appears to be "Johnnie Marbles", an anarchist comedian, who, at least according to his Twitter feed, was present in the hearing room. He wrote a few posts criticising the Murdochs' testimony and then concluded with, just before the pieing: "It is a far better thing that I do now than I have ever done before #splat". He reportedly called Murdoch a "greedy billionaire" before hitting with a plate full of shaving cream.
