Three Garda officers have been arrested as part of a corruption probe within the force.
A superintendent, an inspector and a rank-and-file garda were detained this morning.
The superintendent has been arrested on suspicion of the unlawful disclosure of Garda information.
The inspector has been detained over suspected drugs offences, and the garda has been held on suspicion of conspiracy to pervert the course of justice.
Confirming the arrests, Deputy Commissioner John Twomey said: "An Garda Siochana is fully committed to investigating any alleged wrong-doing or corruption involving Garda personnel, and will work with other relevant agencies in doing so.
"As this is a live and ongoing investigation, it is not appropriate to make any further comment at this time."
The arrest operation was led by the Assistant Commissioner for Special Crime Operations, John O'Driscoll.
It involved the Garda National Bureau of Criminal Investigation (GNBCI) and the Garda National Drugs & Organised Crime Bureau (GNDOCB).
