It's reported that the Garda Ombudsman Commission carried out a security sweep of its offices, after a senior Garda appeared to know information about a case being investigated by them.
The Sunday Times reports that the level of detail known by the Garda last summer, was one reason GSOC hired a British firm to examine internal security.
It's understood the Garda had specific information about text that had been removed from a report, but had been discussed at a meeting at the commission's offices.
The Justice Minister Alan Shatter has ruled out an independent inquiry into alleged bugging at GSOC, and the Garda Commissioner insists no members of the force carried out surveillance at its headquarters.
The Justice Minister will appear before the Oireachtas oversight committee this week to answer questions about his actions on the issue.
