The firm, which last month notified the Department of Environment of its intention to drill an exploratory borehole in Co Fermanagh, has condemned Sunday morning's incident.It said: "This was an orchestrated and abhorrent attack on a local family in the middle of the night."We condemn this latest attack that follows a number of unlawful incidents at our Belcoo site and threats that have been made to security staff."It was reported to police that a car drove by a house at Station Road, Letterbreen on Sunday at about 3.25am and a petrol bomb was thrown at the property.A police spokesperson said: "No one is believed to have been injured during the incident and enquiries are continuing."Several anti-fracking protests have been held against Tamboran's plans to drill the exploratory borehole near Belcoo, as the first stage of its exploration for natural gas in Fermanagh."The company is operating within the terms of the licence it was awarded by the Northern Ireland Executive to explore for natural gas in Northern Ireland," the Tamboran statement went on.CHAR(13) + CHAR(10) CHAR(13) + CHAR(10)"We know this behaviour is not reflective of the local people.CHAR(13) + CHAR(10) CHAR(13) + CHAR(10)"Tamboran fully respects the right to peaceful protest. We welcome calls from those who have called for any protests to be peaceful. However, we cannot ignore such attacks."We call on all local political, community and anti-fracking representatives to unequivocally condemn this petrol bombing attack and to encourage people to share any information they have with the PSNI".Ulster Unionist MLA Tom Elliott said: "There is no excuse for such dangerous, criminal activity. The wider public must be allowed to have its opinions free from such intimidation."While many people, including myself, have concerns about the proposals to carry out fracking in Fermanagh it does not justify terrorist type campaigns against the process and those involved in it."Police want to speak to the driver of a dark coloured Audi estate car which was seen in the area at the time of the incident, who may be able to assist with their enquiries.The PSNI are appealing to anyone who witnessed the petrol bombing to come forward.
