ELIZABETH JACKSON: The man accused of hacking phones for the News of the World has defended himself in a statement through his lawyers saying he was only following instructions.



The statement comes as a parliamentary committee says it's likely to recall James Murdoch to clarify evidence that he gave which was later challenged by former staff.



Brooke Bowman reports from London.



BROOKE BOWMAN: A day after it was alleged the phone of a grieving mother was hacked, the police officer investigating her daughter's murder says he fears his phone may have also been targeted.



MARTYN UNDERHILL: I believe my phone was hacked by the News of the World and I contacted Operation Weeting just over two weeks ago to report that suspicion.



BROOKE BOWMAN: Detective Martyn Underhill was in charge of liaising with Sara Payne, the mother who is the latest to discover she was a phone hacker's victim.



Now the private investigator at the centre of it all has broken his silence, revealing he was told to hack.



Glenn Mulcaire, who's already faced jail time for phone hacking, is under further investigation with police looking at thousands of allegations.



His lawyers released a statement saying "as an employee he acted on the instruction of others", and that "any suggestion he acted unilaterally, is untrue".



There's still pressure on News International boss James Murdoch. At last week's parliamentary committee he professed ignorance about an email that may have shown phone hacking went beyond one rogue reporter.



TOM WATSON: Did you see or were you made aware of the for Neville email, the transcript of the hacked voicemail messages?



JAMES MURDOCH: No, I was not aware of that at the time.



BROOKE BOWMAN: The committee members are likely to ask him to return.



Committee chairman John Whittingdale says he needs more information.



JOHN WHITTINGDALE: What I want to have is the detailed submission from those individuals who dispute part of James Murdoch's evidence so that we can then question him about that. At the moment all we've got is a very brief statement from them saying we don't agree.



If we are to re-examine James Murdoch we need to know more about the areas in which they say that he's wrong, but certainly it is our intention to pursue that and I think it very likely that we will wish to hear from him.



BROOKE BOWMAN: The Murdochs may have felt some justice today.



The man who threw a foam pie in Rupert Murdoch's face pleaded guilty to assault. But as he walked from court the comedian had a parting shot of his own.



JONATHAN MAY-BOWLES: I'd just like to say that this has been the most humble day of my life.



Thank you very much.



BROOKE BOWMAN: Jonathan May-Bowles will be sentenced early next month.
