North Wales Police is investigating two separate livestock attacks at the same location on land at the rear of CwmAlis Road, Fron, Wrexham.
The force is appealing for witnesses of the attacks, which took place on the weekend of June 8 and June 9 and on June 17.
It is believed that two dogs were involved in the incidents.
North Wales Police said: “Clearly there is a real issue at this location and these dogs need catching before more sheep are killed.”
The force is urging anyone with information to contact it via web chat on the force website or by 101 quoting incident reference 24000545206.
Shooting of gulls
North Wales Police rural crime team is currently receiving numerous reports of the illegal shooting of gulls in Denbighshire and Abergele Coastal areas, as well as the deliberate act of destroying the nests when in use.
PC Bennett from the team said: “The Wildlife and Countryside Act 1981 provides legislation that protects all wild birds, including gulls and their nests, eggs and chicks.
“It is illegal to deliberately kill, injure or take gulls except under licence. The use of an air rifle in these circumstances may also constitute a firearms offence.”
Head of UK investigations for the Royal Society for the Protection of Birds (RSPB), Mark Thomas, said: “Like all wild birds in the UK, gulls and their nests and eggs are fully protected under the Wildlife and Countryside Act 1981.
“It’s a criminal offence to intentionally kill, take or injure them or destroy their nests and/or eggs and committing these types of offences could result in a significant fine or time in prison.
“Anyone with information about the illegal shooting or harming of Gulls should contact the police immediately on 101.”
Royal Society for the Prevention of Cruelty to Animals (RSPCA) scientific and policy officer Rebecca Machin said: “We should all want to live in communities where our wildlife is treated with kindness.
“Herring gulls in particular are a species of conservation concern in the UK and their populations are in decline.
“Sadly, many people have an unfavourable opinion of them and we know they can even be targeted – but these are intelligent animals who form strong social bonds with each other, and deserve to be treated with respect.”
