London: The police probing the phone- hacking issue on Tuesday made another arrest of a man reported to be a key figure at Rupert Murdoch's News International.

The unnamed man apparently did not know he was going to be taken into custody when he arrived by appointment at a police station in London this morning to answer questions about the phone-hacking scandal, The Guardian reported.

Police from both Operation Weeting, the Metropolitan police investigation into phone hacking, and Elveden, the investigation into allegations of inappropriate payments to police, were reported to have been involved in the arrest.

The development is the latest in a scandal that has already caused the closure of a 168-year-old newspaper, the News of the World, and the resignation of two top police officers, as well as 10 arrests.

The Guardian reported: "The arrested man is believed to have been a key figure at News International. He is understood to have been arrested on suspicion of conspiring to intercept communications... and on suspicion of corruption allegations".

They are the same allegations that Rebekah Brooks, the former News of the World editor and ex-News International chief executive, faces since her arrest last month.

Others arrested and bailed have included Brooks, ex-NoW editor Andy Coulson, ex-NoW assistant editor Ian Edmondson, ex-NoW chief reporter Neville Thurlbeck, senior ex-NoW journalist James Weatherup, freelance journalist Terenia Taras, an unnamed 63-year-old man, and ex-NoW royal editor Clive Goodman.
