A retired assistant Garda commissioner, who was previously involved in investigating complaints of alleged disciplinary breaches in the force, told how it is a “terrifying” ordeal for a serving garda to be put on suspension accused of wrongdoing.

Fintan Fanning was giving evidence at the trial of retired Supt Eamon O’Neill and four serving gardaí, Sgt Anne Marie Hassett, Sgt Michelle Leahy, Garda Tom McGlinchey and Garda Colm Geary.
