Police have launched an appeal for information after loose dogs killed 16 sheep and caused injuries to a further 30 sheep that will require the animals to be put down.
The incident happened in the East Bergholt area of Suffolk on the evening of December 20.
Sergeant Brian Calver from the Rural and Wildlife Crime Team said the incident was "by far the worst case of an attack on sheep" the force had come across.
"The suffering the animals must have gone through would have been terrible.
Dog ownership is a responsible thing so please remember, dogs that are allowed to worry livestock on agricultural land is an offence under the Dogs Worrying Livestock Act.
"Anyone who saw the dogs that were responsible or can describe them please get in touch with us."
Police are asking anyone with information to contact Suffolk Police station, quoting crime reference 37/73715/20.
