Prison officers at the Midlands Prison Portlaoise.
The Gardaí are 'engaged' in examining the use of car tracking and listening devices in the prison system, according to the Minister for Justice Charlie Flanagan.
Speaking in Mullingar, Minister Flanagan briefed reporters on the response to revelations about alleged covert surveillance of prison offers and inmates in the prison system.
The Irish Prison Officer Association had earlier called on the Gardaí to be called in after it was claimed that tracking devices were being used on private cars and prison vehicles driven by their vehicles.
"The gardaí have a very important role to play in examining wrong-doing, and I understand that gardaí are actively engaged on the matter of this issue," he said.
Use of devices, cameras to monitor staff and prisoners are among allegations contained in a sworn statement to Laois TDwho has a large prison complex in his constituency in Portlaoise.
The claims were made via a solicitor because the whistleblower had no confidences in the Irish Prison Service protected disclosures.
