British police on Saturday arrested a police officer and four former and current journalists with the 'Sun' newspaper as part of continuing investigation into the phone-hacking controversy at papers owned by Rupert Murdoch's News Corporation.
The five were arrested under Operation Elvedon, which is investigating the payment of money to police officers by journalists for information to be used in sensational stories.
Scotland Yard said the five men, aged 29 to 56, were arrested at addresses in London and Essex earlier.
The 29-year-old, a serving officer in the Metropolitan Police's Territorial Policing Command, was arrested at his office in a central London police station.
As per standard practice, Scotland Yard did not release the names of those arrested but according to the BBC, the four arrested journalists are ex-deputy editor Fergus Shanahan, ex-managing editor Graham Dudman, crime editor Mike Sullivan and head of news Chris Pharo.
Offices at News International in Wapping were being searched.
News Corporation and its Management and Standards Committee (MSC) issued a statement following the arrests, saying it had made a commitment last summer that unacceptable news gathering practices by individuals in the past would not be repeated.
