Four journalists were arrested today in connection with a suspected conspiracy to intercept telephone voicemails at Mirror Group Newspapers, according to Scotland Yard.

As part of the inquiry four people were arrested at separate addresses at approximately 6am this morning on suspicion of conspiracy to intercept telephone communications contrary to the Criminal Law Act 1997.

On 11 July last year, Sunday Mirror crime correspondent Justin Penrose was arrested on suspicion of conspiracy to cause misconduct in a public office.
