Another member of the force has been arrested for suspected "conspiracy to pervert the course of justice".
A garda superintendent has been arrested for suspected breach of the provisions of section 62 of the Garda Síochána Act, 2005.
Section 62 of this Act states that a person who is a member of the Garda Síochána shall not disclose any information obtained in the course of carrying out duties of that person’s office, employment, contract or other arrangement if the person knows the disclosure of that information is likely to have a harmful effect.
It is not clear what station or county the arrested Gardai are based in.
In a statement, Deputy Commissioner John Twomey said: "An Garda Síochána 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 three gardai are in custody and are detained for the purpose of questioning arising from suspicion that they have been involved in the commission of one or more criminal offences.
