Scotland Yard Tracking Down Secret Rupert Murdoch Tape The Guardian

Scotland Yard is on the case of a secret recording of News Corp. mogul Rupert Murdoch. The U.K. newspaper The Guardian reports that Scotland Yard detectives are hunting for the tape, which reportedly captures Murdoch admitting to Sun journalists that payments to public officials were part of "the culture of Fleet Street."

British authorities have made a formal request to Exaro News, which broke the story, to provide the undercover recording, the story says.

"DCI Laurence Smith told Exaro News that the police would seek a production order compelling it to disclose the recording if it did not do so voluntarily. It is understood the police have also approached Channel 4, which aired a small part of the recordings," the story reports.

The piece adds: "The development is the clearest indication yet that police in London are ready to examine Murdoch's private disclosures since the tapes emerged on Wednesday night."
