Senior Surrey detectives investigating the disappearance of Milly Dowler held two meetings with journalists from the News of the World and were shown evidence that the paper held information taken from the voicemails of the murdered schoolgirl.
An investigation by the Independent, which focuses on this crucial period of the phone-hacking scandal, reveals that the force subsequently failed to investigate or take action against the News International title.
One of the officers at the meetings was Craig Denholm, now Deputy Chief Constable of Surrey. He was the detective chief superintendent in charge of Operation Ruby, the codename for the investigation begun after the teenager disappeared on March 21, 2002.
The Independent Police Complaints Commission is investigating claims that a junior detective on Operation Ruby passed information gathered by the inquiry to the News of the World. According to Surrey police, the officer was removed from the investigation after he passed confidential information about it to a friend outside the force.
The Independent has confirmed the identity of the officer, who is still a member of the Surrey force. But his name is being withheld after a claim from his lawyers that identifying him could prove "catastrophic" for him and his family because of public anger at the hacking of Milly's phone.
