Prosecutors yesterday announced they would take no further action in Britain's mammoth phone-hacking probe, ending a four-year investigation. The Crown Prosecution Service (CPS) said it would take no further action against News Group Newspapers (NGN), global media baron Rupert Murdoch's British tabloid stable. The probes into voicemail interception and other alleged media crimes amounted to the biggest police investigation in British history. The scandal led to the demise of the expose-led News of the World weekly tabloid, which was Britain's big-gest-selling newspaper.
