The directors of Quinn Industrial Holdings (QIH) have reportedly received another death threat, informing them that this is their "last warning".

The threat, delivered to the Irish News newspaper on Monday, was conveyed to Quinn directors living in Fermanagh and Cavan last night by police on both sides of the Border.

It is reported that the directors were told in the threat this was their “final warning” -- over a month after Kevin Lunney was abducted and assaulted and “left for dead”.

The directors have been informed by the letter-writers that they “could have killed Kevin very easily" and told they had not learned their lessons after what happened.

It is reported that the letter also threatened Cavan County Council staff or other contractors who remove posters erected as part of the campaign of intimidation against the directors. It warned that they will be targeted if they remove the posters.
