'I don't believe there was an attack launched on Sgt McCabe,' Nóirín O'Sullivan tells Charleton Tribunal

Former Garda Commissioner Nóirín O'Sullivan has told the Charleton Tribunal that she had done nothing that would threaten the role of garda whistleblower Sgt Maurice McCabe.

The tribunal has heard how Sgt McCabe resigned his position as sergeant-in-charge of the traffic division in Mullingar on May 18, 2015, while the garda commissioner's legal team had told the O'Higgins Commission they were instructed to question Sgt McCabe's credibility and motivation in making complaints.
