A 48-year-old man was arrested at an address outside London this morning by Scotland Yard officers in connection with allegations of "inappropriate payments to police".
The Met said in a short statement that the unnamed man was detained on suspicion of corruption as part of Operation Elveden.
That probe, supervised by the Independent Police Complaints Commission, is investigating claims of illegal payment to Scotland Yard officers by newspapers.
Police reopened their inquiry into phone-hacking allegations at News International's now-defunct tabloid News of the World in January this year, by ordering a fresh investigation dubbed Operation Weeting.
The latest arrest relates only to Operation Elveden and not Operation Weeting, however.
The Yard said that the 48-year-old man was in the process of being taken to a police station in southwest London. ®
