A senior counter-terrorism detective has been found guilty of trying to sell information to the News of the World.

Detective Chief Inspector April Casburn committed a "gross breach" of the public's trust by calling the now-closed tabloid and offering details of the phone-hacking investigation in return for payment.

The 53-year-old was found guilty of one count of misconduct in public office by jurors at Southwark Crown Court.

April Casburn was found guilty of trying to sell information to the News of the World

She telephoned the Sunday newspaper early on 11 September 2010 and spoke to journalist Tim Wood, complaining about pressure from Lord Prescott over the probe and giving the names of two former NotW journalists under investigation - Andy Coulson and Sean Hoare.

Casburn, from Hatfield Peverel in Essex, remained impassive as the verdict was given.

Prosecutors said she tried to undermine the hacking investigation by offering to leak details to a tabloid newspaper .

Mark Bryant-Heron told the jury: "She sought to undermine a highly sensitive and high profile investigation at the point of its launch.

"It was a gross breach of the trust that the public places in a police officer not to disclose information on a current investigation in an unauthorised way, or to offer to do so in the future for payment."

He said that her conduct was "disgraceful" and the phone call was "malicious".

Casburn admitted contacting the newspaper, but denied asking for money or offering any information that was not already in the public domain.

She was not working on the probe, called Operation Varec, but colleagues in the counter-terrorism command were running the investigation.

The detective, who joined the force in 1993, claimed she feared colleagues saw the phone hacking probe as "a bit of fun", getting to travel and meet celebrities, and worried about counter-terrorism resources being wasted.

"They thought it was all going to be a bit of fun, getting to travel, getting to see famous people.

"I felt sufficiently strongly we should not be diverting resources which are to do with saving people's lives," she said during the trial.

But Bryant-Heron said that she had not mentioned these concerns in the call, according to an email written by Wood 15 minutes later.
