A prison guard from Northampton and a former police officer were due to be sentenced today/wed after admitting selling information to The Sun newspaper.
High security prison officer Richard Trunkfield, aged 31, from Moulton, both admitted misconduct in public office last month.
Today at the Old Bailey Tierney will be sentenced for two counts - one between March 26 and April 3, 2009, and a second between December 2 and 7, 2009.
He sold details about Sue Terry and Sue Poole, the mother and mother-in-law of former England football captain John Terry, being arrested on suspicion of shoplifting in Surrey.
He also sold details about the arrest of guitarist Ronnie Wood, 65, on suspicion of beating up his Russian lover Ekaterina Ivanova, who is in her 20s.
Terry, Poole and Wood all accepted cautions over the matters.
When he entered his guilty pleas earlier this month, Tierney, 40, from Hayling Island, Hampshire, was warned by Mr Justice Fulford that “all options remain open”.
In a separate case, Trunkfield, admitted leaking information about a high profile prisoner to the tabloid newspaper.
He pleaded guilty to misconduct in a public office between March 2 and April 30, 2010.
A second former police officer is also facing sentence today for the offence, but no further details can be reported for legal reasons
