Scotland Yard officers arrested a 33-year-old man this morning on suspicion of theft offences, computer misuse and conspiracy to pervert the course of justice.
The unnamed suspect is a journalist, the Met said, who attended a south London police station by appointment. He remains in custody.
"The arrest relates to a suspected conspiracy involving the gathering of data from stolen mobile phones and is not about seeking journalists to reveal confidential sources in relation to information that has been obtained legitimately," the Yard said.
It's the latest cuffing in the Met's investigation of alleged computer hacking offences under Operation Tuleta, which is a separate probe relating to the phone-hacking inquiry (Op Weeting) and claims of corrupt payments to police (Op Elveden) that has consumed News International, the Rupert Murdoch-owned newspaper-publishing arm of News Corporation.
Op Tuleta officers have nabbed 12 suspects so far in relation to computer hacking and privacy breaches, while 43 people have been arrested under Op Elveden and 25 manacled under Op Weeting.
The Met's exiting Deputy Assistant Commissioner Sue Akers told Parliamentarians earlier this week that those three investigations could cost the British taxpayer £40m over four years. ®
