A former News of the World chief reporter will not be prosecuted over allegations of intimidating a witness in Scotland Yard's phone-hacking inquiry.

Neville Thurlbeck will not be charged after four files relating to the investigation were handed over by detectives.

Allegations of harassment and witness intimidation related to a blog posted by Mr Thurlbeck, who remains on bail in relation to voicemail interception allegations.

Mr Thurlbeck, 50, told the Press Association: "I am pleased that the CPS has advised the police that no further action should be taken with regard to an allegation concerning one of my blog postings on nevillethurlbeck.com. I would like to thank my family, friends and colleagues in the industry for their unswerving loyalty, support and continued belief in me."

Mr Thurlbeck wrote the blog on March 7, giving the home address of a member of News Corporation's Management and Standards Committee.

Alison Levitt QC, the top legal adviser to the director of public prosecutions, said the Crown Prosecution Service confirmed one of the four files referred to Mr Thurlbeck.

She said: "Having applied the full test set out in the code for Crown prosecutors the CPS has concluded that no prosecution should take place. Given that the journalist in question remains on bail for further offences we do not intend to give any further information at this point.

"Mr Thurlbeck remains on police bail on suspicion of offences under Regulation of Investigatory Powers Act 2000."

Sunderland-born Mr Thurlbeck was behind stories including disclosures about ex-Formula 1 boss Max Mosley's sex life and allegations that David Beckham had an affair.
