Policeman suspected of leaking details of hacking investigation as force also confirms arrest of 35-year-old man.
Phone hacking: the man has not been charged but he has been suspended by the Metropolitan police.
A police detective has been arrested on suspicion of leaking details about Scotland Yard's phone-hacking investigation.
The man has not been charged but he has been suspended by the Metropolitan police.
The Met also on Friday arrested a 35-year-old man, who Sky News named as former News of the World reporter Dan Evans, on suspicion of phone hacking. He has been released on police bail.
Evans was suspended by the paper more than a year ago after being named in a civil case against the now defunct tabloid's publisher, News International subsidiary News Group Newspapers, brought by interior designer Kelly Hoppen.
Sue Akers, the force's deputy assistant commissioner, who is leading the investigation into phone hacking at the News of the World, said: "I made very clear when I took on this investigation the need for operational and information security. It is hugely disappointing that this may not have been adhered to."
Akers added: "The MPS [Met] takes the unauthorised disclosure of information extremely seriously and has acted swiftly in making these arrests."
A spokesperson for Guardian News & Media, which publishes the Guardian, declined to comment on reports that the leaks had been to the Guardian, and said: "We note the arrest of a Scotland Yard detective on suspicion of misconduct in a public office relating to unauthorised disclosure of information.
"On the broader point raised by the arrest, journalists would no doubt be concerned if conversations between off-the-record sources and reporters came routinely to be regarded as criminal activity. In common with all news organisations we have no comment to make on the sources of our journalism."
