A former prison officer and three others have been arrested for allegedly making payments to public officials.
The former prison officer and his partner were held on suspicion of aiding and abetting misconduct in a public office and money laundering. Another man, believed to be a journalist, was arrested on suspicion of conspiracy to corrupt and conspiracy to cause misconduct in a public office.
The arrests bring the total number of people arrested by officers from Operation Elveden to 33. Scotland Yard said that the arrests were prompted by information supplied by News Corporation’s management standards committee.
