Gardaí and the Police Service of Northern Ireland are investigating incidents that caused over €1 million worth of damage to equipment at a company’s premises in Co Cork and Co Down.

Lagan Asphalt Group’s premises in Carrigtwohill, Co Cork and Comber, Co Down were broken into over the weekend and attacks took place on various types of machinery, some of which were set ablaze, causing in excess of €1 million of damage.

In a statement tonight the company claims the damage to equipment at the sites is related to the Lagan Cement Group's recent announcement about the acquisition of the Quinn Rooftiles business in Derrylin, Co Fermanagh.

The statement also called on elected and public representatives to condemn what it called unlawful acts and those who carry them out.

The company said it is assisting the Gardaí and PSNI with their investigations.

Lagan is a major construction and civil engineering company with a range of operations in Ireland and the UK.
