A former Woodhill Prison officer has pleaded to guilty to selling information to The Sun.
Richard Trunkfield appeared at the Old Bailey today to admit misconduct in a public office charges.
The 31-year-old from Northamptonshire made his plea alongside two former police officers and another public official.
Ex-Surrey police constable, Alan Tierney, and another police officer, who cannot be named, also pleaded guilty to misconduct in a public office. A fourth person, who also cannot be named for legal reasons, pleaded guilty to an offence of conspiracy to commit misconduct in public office.
All four were arrested as part of Scotland Yard Operation Elveden probe into alleged illegal payments by journalists to police and other public officials.
Trunkfield pleaded guilty to selling information about a “high-profile prisoner” to The Sun.
The former operational support officer at Woodhill was alleged to have received £3,350 for information he provided to the paper on two occasions between March and April 2010.
He will be sentenced later this year.
