The Disclosures Tribunal has heard a Garda whistleblower felt like a "sitting duck" after making a protected disclosure about alleged wrongdoing in the force.
The tribunal has begun hearing evidence from Garda Nicholas Keogh, who raised concerns about the drugs unit in Athlone Garda Station.
Garda Nicholas Keogh made a protected disclosure in 2014 about the Drugs Unit in Athlone Garda Station, and alleged interaction with a "Garda A" and a woman "Miss B", who Garda Keogh alleged in a Pulse entry was involved in drug dealing and had a weekly "turnover of approximately €2,500".
Garda Keogh claims he's been targeted since making the disclosure and was a "sitting duck".
The tribunal is solely focusing on 22 issues contained in his complaint to it.
It heard he alleges he was under "micro supervision" by three Sergeants, his travel expenses were delayed, and he was confined to desk duty.
In a statement to the Tribunal, Garda Keogh claimed then Garda Commissioner Nóirín O'Sullivan contacted the District Officer in Athlone about him in April 2015.
Whether the tribunal will examine this allegation, which Nóirín O'Sullivan told it is "completely untrue and without foundation", will be decided on Wednesday.
