Whistleblower tells tribunal heroin dealer's 'incredible' admission was 'sat on for five months' by Gardaí

A Garda whistleblower has told a tribunal that he has a "huge issue" on whether or not his complaints were being investigated in good faith because of an "incredible" admission by a heroin dealer that was "sat on for five months".

Garda Nicholas Keogh is giving evidence at the Disclosures Tribunal, where counsel for An Garda Síochána are cross-examining him.
