Four sheep including a ram have been found killed in a field in Oxfordshire, with all the edible parts stolen.
The remains of the four animals were discovered off the B4449 Aston Road, near Witney. It is thought they were killed overnight.
The animals, worth about £2,000, included three pedigree sheep from the Texels breed and a pedigree ram from the Bleu Dumaine breed.
Police said it appeared the sheep were butchered at the scene for their parts.
Pc Simon Towers, wildlife officer for Oxfordshire, said: "This is a very nasty crime that would have caused great suffering to the animals and has left the owner of the livestock very distressed.
"I would urge anyone with information about this incident to come forward and speak to us as soon as possible."
