Norfolk farmers are being encouraged to display signs warning that hare coursers found on their land face prosecution and heavy fines.
The signs ask people to call 999 immediately if they see coursing taking place. Police will seize and destroy vehicles used by the criminals.
The initiative, funded by the CLA, NFU and the Norfolk Police, aims to tackle the activity which becomes more prevalent at the end of harvest when large areas of land are left without standing crops.
CLA East regional director Ben Underwood said: “Norfolk is often targeted by hare coursers who trespass on private land to carry out this illegal activity. The sign is designed to raise awareness as many people don’t realise how big a problem this is in the countryside.”
