In an internal email, News International boss Mike Darcey, said he shared colleague's concerns about today's arrests.
Because this now means that with all the phone-hacking investigations, the computer hacking, illegal payment to officials, more than 100 people have now been arrested. More of half of them are journalists.
This is a new twist in the phone hacking investigation. The police have already made arrests and some charges like Rebecca Brooks and Andy Coulson on phone hacking.
But today they made clear that this is a new inquiry into the separate phone hacking allegations from 2005 and 2006.
So there are potentially new victims out there that don't know that there phones have been hacked and the police are now going to be in contact with them.
The six people arrested today are all former News of The World journalists .
Former head of features, Jules Stenson, former showbiz columnists Rav Singh and Polly Graham, Matt Nixson and two journalists - who now work for The Sun - Jane Atkinson and Rachel Richardson.Tonight, Scotland Yard said that five of the six people arrested have been released on bail.
Five people arrested on suspicion of phone hacking have been released on police bail, Scotland Yard has said.
The individuals had been interviewed at various police stations in London and Cheshire and searches were carried out at a number of addresses, the force added. A 39-year-old man arrested in Greenwich remains in police custody.
A Met spokesman said: "In due course officers will be making contact with people they believe have been victims of the suspected voicemail interceptions."
Six former News of the World journalists have been arrested under a new police investigation into phone hacking. Three men and three women were all held today under a suspected conspiracy, that took place around 2005 and 2006.
They 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.
The arrests, five in London and one in Cheshire, were made as part of a new line of inquiry that is separate from allegations under the existing Scotland Yard investigation into phone hacking called Operation Weeting.
The significance of the new phone hacking arrests is that police say these are new allegations with possibly new victims, separately from the ones already being investigated.
An internal message has been sent to News International employees confirming that two of those arrested are journalists currently working for The Sun.
The pair have been provided with lawyers.
Police believe this latest suspected conspiracy took place primarily during 2005 to 2006 and is separate from the alleged conspiracy already being investigated by Operation Weeting in which a number of people have already been charged.
As part of the new lines of inquiry six people were arrested this morning on suspicion of conspiracy to intercept telephone communications All of them are journalists or former journalists:
- A 46-year-old man was arrested in the London Borough of Wandsworth
- A 39-year-old man was arrested in the London Borough of Greenwich
- A 45-year-old man was arrested in the London Borough of Wandsworth
- A 39-year-old woman was arrested in Cheshire
- A 33-year-old woman was arrested in the London Borough of Islington
- A 40-year-old woman was arrested in the London Borough of Lambeth
All six of those arrested worked for the News of the World.
Six current and former journalists in London and Cheshire 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.
A number of high profile phone-hacking cases are to be settled at the High Court today.
It is the latest in a series of case management conferences, ahead of a hearing in June.
At that time, compensation will be assessed in any outstanding claims for the second wave of the litigation.
Agreed statements of around 15 claimants could be read out to Mr Justice Vos today, with an estimated 160 claims on the register, and more coming forward.
Actress Sienna Miller was the first to publicly settle her privacy and harassment claim, for £100,000, in June 2011, with her ex Jude Law receiving the highest pay out so far, with compensation of £130,000.
Sentencing, Mr Justice Fulford told April Casburn she had been guilty of "a corrupt attempt to make money out of sensitive and potentially very damaging information".
The judge went on:
Activity of this kind is deeply damaging to the administration of criminal justice in this country.
It corrodes the public's faith in the police force, it can lead to the acquittal or the failure by the authorities to prosecute individuals who have committed offences whether they are serious or otherwise.
We are entitled to expect the very highest standards of probity from our police officers, particularly those at a senior level.
It is, in my judgment, a very serious matter indeed when men or women who have all the benefits, privileges and responsibilities of public office use their position for corrupt purposes.
He said he was particularly concerned about Casburn's child, and admitted that her absence while she is in prison could be damaging.
But he said that, had she not been arrested, the detective would have returned to work by now, and therefore the child would be cared for by others anyway.
