The garda whistleblower Maurice McCabe is denying that the Garda Commissioner wrote to him and directed him to co-operate with the garda investigation into the cancellation of penalty points.
In a statement issued last night, Sergeant McCabe said media reports about Martin Callinan's directions to him are "gravely misleading and false".
Maurice McCabe vehemently denies he was ever instructed to cooperate with an inquiry into the penalty points issue by Assistant Commissioner John O'Mahony.
Sergeant McCabe says the O'Mahony report was completed without any input from him, and that he had protested that he was not contacted by the inquiry.
He claims that on the 14th December 2012 he was given verbal instructions from a senior garda which came directly from the Garda Commissioner Martin Callinan.
Sergeant McCabe says the direction was for him to desist from the accessing the Pulse system and disclosing data on the cancellation of penalty points by Gardaí to a third party/
The direction said if Sergeant McCabe had any further concerns about the matter he should bring them to the attention of Assistant Commissioner O Mahony.
Meanwhile Cabinet ministers will gather here this morning for their weekly meeting and may sign off on an independent inquiry into the allegations surrounding garda handling of serious crimes.
Justice Minister Alan Shatter, who's faced calls to resign over the issue, will brief the Cabinet on what he knew and when.
