Three people have been arrested by police investigating allegations of inappropriate payments to public officials by journalists, Scotland Yard said.
A 39-year-old serving officer with Wiltshire Police was arrested at his home in the county by officers working on Operation Elveden, the Metropolitan Police said.
At the same time a 51-year-old journalist was arrested at his home in Bristol and a 32-year-old journalist was held at his house in south-east London, both on suspicion of conspiracy to corrupt and conspiracy to cause misconduct in a public office.
A Metropolitan Police spokesman said: "Today's arrests are the result of information provided to police by News Corporation's management standards committee.
"They relate to suspected payments to a public official and suspected disclosure of confidential information by a police officer and are not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately."
