A journalist from The Sun newspaper was arrested today by police investigating alleged computer hacking.
The individual has been named by Press Association as Sun reporter Rhodri Phillips.
Scotland Yard said he was held at his home in north London this morning by police working in conjunction with the phone-hacking investigation.
A spokesman said: "Officers from Operation Tuleta, the investigation into criminal breaches of privacy which is being carried out in conjunction with the Metropolitan Police Service phone-hacking inquiries, arrested one man at his home in north London at approximately 6.30 this morning."
He is the seventh person to be arrested as part of Operation Tuleta computer hacking inquiry.
So far, 24 people have been arrested as part of the phone-hacking inquiry, and 41 as part of an investigation into alleged corrupt payments to officials, Operation Elveden.
At least 30 journalists have been arrested and bailed pending possible charges as a result of three inquiries.
