A journalist has been arrested as part of the Metropolitan Police?s inquiry into allegations of computer hacking.
The man, understood to be 28-year-old reporter Patrick Foster, was arrested in London as part of Operation Tuleta.
The Met says he is ?being questioned about alleged computer hacking relating to the identification of a previously-anonymous blogger in 2009?.
It is believed it relates to the outing of an police blogger known as Nightjack, by the Times in 2009.
He is the 11th person to be arrested by detectives from Operation Tuleta which is taking place alongside the phone-hacking scandal investigation, Operation Weeting.
Mr Foster was also arrested on suspicion of conspiracy to pervert the course of justice.
He is being questioned at a north London police station.
