Scotland Yard officers arrested a 28-year-old man this morning on suspicion of computer hacking relating to the identification of a previously anonymous blogger in 2009.
The Met said the suspect is a journalist and that he was cuffed as part of the force's Operation Tuleta investigation into alleged computer hacking by newspapers.
The man was collared in north London for suspected offences under the Computer Misuse Act 1990 and suspected conspiracy to pervert the court of justice, contrary to the Criminal Law Act 1977, police said.
Scotland Yard did not reveal the name of the journo being questioned. It also kept the aforementioned one-time anonymous blogger's identity secret in its statement.
However, the BBC is reporting that the journalist in question is ex-Times scribe Patrick Foster, who outed an anonymous police officer blogger known as NightJack in the Rupert Murdoch-owned newspaper back in 2009. Foster left the paper in 2011 to write for the Guardian and the Daily Telegraph. ®
