Two former prison officers have been arrested in connection with Scotland Yard's inquiry into alleged inappropriate payments to police and public officials.
The 47-year old man and 44-year-old woman were arrested by Operation Elveden officers at an address in Suffolk.
They were arrested for alleged misconduct in a public office and conspiracy to commit misconduct in a public office and are in custody at a police station in Suffolk.
There have now been 89 arrests under Operation Elveden which is looking at allegations of inappropriate payments.
It is being supervised by the Independent Police Complaints Commission and is running alongside Operation Weeting, the Metropolitan Police's phone-hacking inquiry.
