Quinn Group boss Liam McCaffrey under death threat
Management team is also warned in letter delivered with three bullets
A death threat has been issued to a man who took over parts of the former Quinn Group, as well as other members of the company's management team.
The PSNI and An Garda Siochana have launched a cross-border investigation into the move against Quinn Industrial Holdings Limited boss Liam McCaffrey, who was the chief executive of Quinn Group.
It is understood that the PSNI has told Mr McCaffrey and his colleagues to review their security arrangements.
The handwritten letter was sent to staff at energy firm Vestas - formerly owned by Quinn Group - warning them to "stay away" from a windfarm or "face the bullet" and noting it was a" final warning". The letter came with three bullets, according to the Impartial Reporter.
It has also been learned a worker at the Slieve Rushen windfarm on the Fermanagh and Cavan border was recently threatened by a man with a rifle as attempts were made to block access. And last week, a sabotage attempt on a lorry at one of the firm's factories in the Ballyconnell Road area of Derrylin resulted in £12,000 of damage.
A spokesman for Quinn Industrial Holdings Limited refused to give details on the matter. "Given the ongoing investigation, we are unable to make comment at this time, other than to note our sadness and concern," they said.
A spokeswoman for Concerned Irish Citizens, a cross-border lobby group, added: "We take this opportunity to unequivocally affirm we do not condone any acts of vandalism, trespass, intimidation or anything that disrupts the safety and rights of others.
"Our objective has always been to give a forum to the hundreds of people, employees, locals, landowners etc who contact us and whose safety and rights they feel are being infringed upon."
The developments, described by one source yesterday as "deeply sinister", are similar to threats, intimidation and attacks against the former Quinn Group after tycoon and company boss Sean Quinn's spectacular fall from grace in 2011.
