Six journalists have been arrested by detectives investigating "a further suspected conspiracy to intercept telephone voicemails by a number of employees who worked for the now defunct News of the World newspaper", Scotland Yard said.
Those arrested are understood to be Jules Stenson, Matt Nixson, Rav Singh, Jane Atkinson, Polly Graham and Rachel Richardson.
Ms Richardson and Ms Atkinson both work for The Sun and have been provided with lawyers.
The three men and three women have been arrested in what police said was a new line of enquiry into phone hacking.
A police statement said: "This suspected conspiracy is believed to have taken place primarily during 2005 to 2006.
"It is separate from the alleged conspiracy already being investigated by Operation Weeting in which a number of people have been charged."
A police spokesman said: "In due course officers will be making contact with people they believe have been victims of the suspected voicemail interceptions."
Five of those arrested were later released on bail but a 39-year-old man arrested in Greenwich, south London, remains in custody, police confirmed on Wednesday evening.
