The mother of one of the victims killed in London’s 7/7 bombings is suing The News Of The World for alleged phone hacking, the Guardian reports.

Sheila Henry, mother of Christian Small instigated the action after being informed by Scotland Yard that her son’s phone was hacked by Glenn Mulcaire, the private investigator working for the now defunct tabloid.

Small, 28, was killed during the 2005 terror attack when his Piccadilly line train was bombed between King's Cross and Russell Square.

His family apparently tried to contact him on his mobile on the day of the blast in an effort to locate him. He was later confirmed dead.

The high court reportedly ruled that Henry’s civil case would be a "lead action" against the paper, which shut down in July after reports emerged that it had hacked the phone of murdered school girl Milly Dowler.

Others bringing actions against the Sunday tabloid include actor Jude Law, MP Chris Bryant, interior designer Kelly Hoppen, ex-footballer Paul Gascoigne and comedian Steve Coogan.

Meanwhile News International boss James Murdoch will return to give evidence on phone hacking to the culture committee after his statements about the extent of his knowledge of the practice at the the tabloid conflicted with evidence provided by other NI executives.
