A serving Metropolitan Police officer has been arrested by detectives investigating alleged corrupt payments to public officials.
The 47-year-old man and a woman aged 48 were held at their home in Surrey by officers from Operation Elveden, Scotland Yard said.
They were arrested at around 6am on suspicion of misconduct in public office and suspected conspiracy to cause misconduct in public office and were being questioned at police stations in Surrey.
The latest arrests bring the number of people held under Operation Elveden to 76.
The investigation is being run alongside two other inquiries led by Scotland Yard – Operation Weeting, which is looking at alleged phone hacking, and Operation Tuleta, which focuses on computer hacking and other alleged privacy breaches.
In August, the force revealed that 38 people had been interviewed under caution as part of the three operations, in addition to the arrests that had been publicised.
This included 19 people who had been questioned under Operation Elveden.
The Independent Police Complaints Commission has also made three arrests under inquiries linked to the investigation.
