Garda chief Martin Callinan says IRA collusion was 'horrifying'
The commissioner of the Irish police, Martin Callinan, has said he is "horrified" that any member of the force would have colluded with the IRA.
The Smithwick Tribunal was set up by the Irish government in 2005 to investigate claims that officers based in Dundalk station had assisted the IRA gang who ambushed the two officers on 20 March 1989.
In the report of his inquiry published on Tuesday, Judge Peter Smithwick said he was "satisfied there was collusion in the murders".
