A warning has been issued to residents over the potential risk of poachers.
In the last few years, police say they have worked 'very closely' with rural communities to 'great success' in the reduction of poaching of wild animals.
Wildlife crime officer Daryl Holter said: “We would like to encourage anyone to contact us with any information that would help in catching poachers, especially if they have been offered meat from sources other than bona fide dealers”.
"I’d also like to send a warning to poachers themselves that we are working very closely with farm and land owners and in some cases even install CCTV to catch poachers. It will not be tolerated and we will do all we can to support anyone that this crime affects.”
A spokesman said: "Poaching is a secretive business, often carried out at night and in remote locations, but if caught, poachers can be prosecuted for a range of offences.
"Game dealers, restaurateurs, hotels and public houses are being advised to check that they are not buying illegally killed game.
"They can do this by not purchasing meat from unknown persons and reporting suspicious gatherings in car parks immediately; dealers in game should show legal documentation for the sale of meat."
On Monday September 16, officers were called to reports of a vehicle with high powered lights seen to be searching farm land near Chichester at 10.30pm.
A gun shot was then heard and police said the person did not have permission to be on the land.
