Inspector McDermott added: "Rural crime can have a significant effect on the farming community. Ask yourself, how can I protect my property, livestock, home and livelihood? One of the ways to protect your farm and livestock is by checking fields where the stock are grazing; keep the hedges, fences and gates in good repair. Keep all sheds and stockyard gates closed and locked. Livestock identification is essential. Take photographs or videos of valuable animals with the brand and/or ear tags clearly visible. Maintain accurate livestock records.
"Be a good neighbour - In all aspects of farm security good neighbourliness and vigilance are the most effective deterrent against crime. So watch out for your neighbours and encourage them to watch out for you. Report anything suspicious immediately to the police."
