Rural residents throughout the locality are being warned to keep a lookout for poachers.
Police say they have seen an increase in poaching offences in the area over the past month or so.
A force spokesman said: “Please let us know if you see any vehicles parked up on rural roads late at night particularly the 4x4 type or vans that are often used by poachers.
“We would encourage any farmers to report any sightings of poachers to us and not approach them themselves.
“Recently in the Grimsargh area we have seen poachers stop checked and their equipment seized from them, and on a separate occasion poachers stopped on Eastway and equipment and dogs seized.”
A recent pattern has seen deer carcasses being left on farmland and it is only when dog walkers or land owners find them that police are made aware.
He added: “This is a worrying trend. In the last few days we have had two deer killed by dogs and then the meat stripped off them and carcasses dumped on land near Red Scar industrial estate. We are currently following up on a lead and a vehicle that was sighted in the area.
“Please continue to help by reporting anything suspicious to us at Broughton.”
