Details have emerged today of a second tape recording from 2006, during which a Garda is alleged to have made sexually abusive remarks to a protestor in Bellinaboy.
The Garda Commissioner has received a report into allegations that Gardai threatened to rape two female protesters arrested at the controversial Corrib gas pipeline in Co. Mayo last week.
The file was handed over after an internal investigation into claims officers laughed as they talked about sex attacks on the Shell to Sea activists.
Commissioner Martin Callinan is expected to review the report and consult with senior officers before assessing possible disciplinary procedures.
Both women at the centre of the allegations will make private statements on the affair to the Garda Ombudsman later.
One will also discuss the scandal publicly at a press conference in Dublin later.
