The spying operation was uncovered when the Ombudsman hired security consultants to investigate whether its office had been bugged.
The investigation found that a phone in a meeting room had been rigged to eavesdrop on confidential conversations.
The room was used to hold case conferences related to investigations being carried out by the commission.
The Wi-Fi network at the Garda Ombudsman office had also been hacked - allowing emails and confidential material to be intercepted. (more)
UPDATE:
Mr Shatter has asked the Commission for a report on its decision to hire a British Security company last year to investigate if it had been placed under electronic surveillance.
A source within GSOC has confirmed to RTÉ that the company told it that it had found evidence of electronic surveillance in one of its meeting rooms and that its wi-fi system may have been compromised. (more)
