Three sheep were killed and a further three had to be treated for injuries after being attacked by loose dogs at a farm on the Wiltshire/Dorset border.
The sheep were set upon by dogs in the Semley area in the early hours of Saturday (23 September).
One of the sheep suffered a heart attack and died, while the other two had to be put down as a result of suffering serious injuries.

Three more sheep – two ewes and a lamb – were seriously injured in the attack and they had to be stitched up by a vet.
Ellen Bone, whose father owns the herd, posted disturbing images of the sheep on Facebook.
She appealed to dog owners to ensure their pets are kept on a lead near livestock.
“Just another incident to highlight the importance of keeping your dogs on leads and under control in the countryside,” said Ms Bone.
Police have been alerted and are investigating.
Anyone with information is urged to call 101 or Crimestoppers anonymously on 0800 555 111.
