Police inspector Alan Dron, Scotland’s national rural crime co-ordinator, said SelectaDNA was proving to be a huge success story and he was seeking to widen the scheme in Scotland.

“Combined with proactive policing, an extremely strong local rural crime partnership and a number of criminals being caught and locked up, theft of quads, trailers, plant and machinery has significantly reduced in many parts of rural Scotland,” said Insp Dron.

“As a result of the reduction in theft, we’re going to be giving out more kits to vulnerable farms.”
