Legal teams for the PSNI and Garda commissioner have clashed over the accuracy of intelligence presented to the Smithwick Tribunal which says a detective sergeant was “helping out the Provisional IRA”.
The summary said that retired detective sergeant Owen Corrigan was “keeping both the boys and the organisation well informed and he lets the boys know what the security forces are doing”.
The tribunal is looking at claims that a Garda tip-off allowed the IRA to set up the ambush in which Chief Superintendent Harry Breen and Superintendent Bob Buchanan died on May 20, 1989.
Mr Corrigan has described allegations that he colluded with the IRA as “a monstrous lie”.
Barrister Dermot McGuinness SC for the Garda commissioner said that he would dispute the accuracy of the summary, which was agreed between the PSNI and the tribunal's legal team.
The tribunal later rose to allow lawyers for the PSNI to seek instructions about a letter sent to the Garda commissioner about the intelligence report. Counsel for the PSNI later confirmed that the summary shown at the tribunal did name Mr Corrigan.
