Scotland Yard said in a statement that the officer was arrested on suspicion of conspiracy to corrupt and misconduct in a public office.
London: A serving prison officer in Northampton was arrested on Tuesday morning as part of an operation related to the phone-hacking controversy at media baron Rupert Murdoch`s now closed `News of the World` tabloid.
The 31-year-old officer was arrested under Operation Elveden, which is investigating allegations of inappropriate payments to police and public officials.
The officer is the 44th person arrested under the operation.
Scotland Yard said in a statement that the officer was arrested at his home in Northampton on suspicion of conspiracy to corrupt, contrary to the Prevention of Corruption Act 1906 and on suspicion of misconduct in a public office, contrary to Common Law.
He is currently in custody at a police station in Northampton.
The statement added: "Today`s arrest is the result of information provided to police by News Corporation`s Management Standards Committee.”
"It relates to suspected payments to a prison officer and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately".
Operation Elveden is being supervised by the Independent Police Complaints Commission and is running in conjunction with Operation Weeting, the inquiry into the phone-hacking of voicemail boxes.
