Three people arrested in the Republic of Ireland in connection with the abduction of Quinn Industrial Holdings executive Kevin Lunney have been released without charge.
The two men, aged in their 20s and 40s, and a woman in her 50s were being questioned as part of the investigation. A file will now be prepared for the Director of Public Prosecutions, Gardaí have said.
The businessman was found with serious injuries after being taken from outside his home in Derrylin, Co Fermanagh and then dumped by a roadside across the border in Cornafean, Co Cavan.
He had suffered knife wounds to his face and neck and had one of his legs broken in two places.
His attack came after a number of threats had been made against directors of Quinn Industrial Holdings.
There have been around 70 incidents throughout a five-year campaign of violence and intimidation directed at those running the company since the fall of Sean Quinn - once Ireland’s richest man.
