The directors of Quinn Industrial Holdings have received another death threat.
It was delivered to The Irish News in Belfast last night, and informs the five directors that it's their 'last warning'.
The gardaí have spoken to each of them individually, as part of their investigation.
It follows last month's abduction and torture of Quinn director Kevin Lunney.
The 50-year-old is still recovering from the life-changing injuries he sustained after he was abducted outside his home in Co. Fermanagh.
He was then brutally assaulted and dumped on the side of the road in Co. Cavan.
In a short statetment the company has said "Regrettably, continuing threats are no surprise to QIH.
It is just proof positive that this issue will not be resolved until the paymaster behind it is brought to justice and law and order is restored to this peace-loving community."
