The case has been front-page news in Ireland ever since Mairia Cahill, one of the three women who accused the alleged IRA man of rape, went public in October with her story and accused Sinn Fein leader Gerry Adams of leading a cover-up designed to protect the attacker and silence his victims. Adams denies this.
Cahill and the two other women, who have retained legal anonymity, met the fact-finder yesterday to discuss his investigation.
The investigator, Keir Starmer, said he would report his findings this spring.
