A rural insurer says agricultural theft is on the rise, and this is estimated to have cost the UK farming industry £49.7m in 2010. NFU Mutual said 'agri-crime' on farms has risen from £41m in 2009, with power tools like chainsaws, electric drills and lawnmowers the most stolen items in 2010. The organisation surveyed its branch offices in rural towns and villages and found that two-thirds of branches had reported an increase in rural crime in their area.
