A pig’s head has been left outside the home of a senior member of Quinn Industrial Holdings Limited in Fermanagh as part of a campaign of intimidation against the management team.

The sinister twist is understood to have caused considerable shock to the individual and his family and comes amid renewed calls for the Police Service of Northern Ireland to reveal what it is doing to combat the ongoing problems.

There have been several incidents at the company once owned by discharged bankrupt businessman Sean Quinn in recent months, including death threats, acts of sabotage, discovery of bullets, chilling notes and signs warning executives such as Liam McCaffrey that they “face the gun.”

Last week the owner of a crane hire company was forced to remove his equipment from a wind farm once owned by the Quinn Group before it was “burnt to the ground.”

Sinn Fein’s Sean Lynch has condemned the incident, saying: “Those responsible are seeking to cause fear and intimidation and the local community rejects those involved. This is completely unacceptable and no workers should be under such threats.”

Ulster Unionist MP Tom Elliott said: “I am keen to establish what action the PSNI has taken so far. I would be very interested to know how many arrests and charges there have been in relation to these incidents. I plan to meet with the police to discuss my concerns.”

In a statement last Thursday, Sean Quinn said he has “always criticised the intimidation.”

“However, I am but one voice, and I feel that other people that operate within this community should play their part also,” he added.

As a power battle rages within Quinn Industrial Holdings Limited, Mr. Quinn has for the first time publicly confirmed that he is attempting to regain control of his former company.

“It is no secret that I am engaged in commercial discussions with the US investor group that acquired the Quinn Group in late 2014, and that this process involves the Quinn Business Retention Company and the group’s management team. The discussions with the investor group are private and confidential, however I can confirm that they have been constructive and are ongoing.”

As a bitter dispute between Mr. Quinn and the management of his former company continues, he says that while he has differences of opinion with them on business matters he believes those differences “can be resolved through the commercial discussions which are ongoing.”

Amid the hostility, business appears to be improving after the company turned a €14.6 million loss into a €5.9 million profit last year. New figures published by the group show that turnover rose by 25 per cent to €203 million from €161.7 million.

Mr. McCaffrey said the “continuing support” of the investor group “marks a major endorsement of our strategic direction and future prospects and will assist in our target of delivering a further improvement in profitability and employment in 2016.”
