Four animals have died and 20 more have been injured in a series of sheep worrying incidents in Roslin.
Police have launched a probe following the incidents, which took place at Langhill Farm overnight on November 26-27, November 28-29 and December 15-16.
Sergeant Michele Lindsay at Penicuik Police Station said: “These three incidents happened on the same land and we are treating it as sheep worrying caused by a dog. Because of the rural nature of the area, we do not currently have any witnesses so are keen to speak to anyone who may have any information.
“We are committed to tackling rural crime and are working with farmers, landowners and businesses in the rural parts of Midlothian and our partners such as the NFU Scotland and SSPCA to raise awareness of such crimes and measures that can be taken to prevent them.
“Everyone who uses our rural areas for business or pleasure has a responsibility to keep them safe, and so we would encourage visitors to leave the countryside as they find it and be mindful of not leaving gates open and reporting any damage they might find; and for people who live and work there to ensure they keep their land and property secure, mark property and report any crimes or concerns to their local officers.”
Anyone with information should contact Police Scotland on 101 or Crimestoppers anonymously on 0800 555 111.
