Police forces in our region have launched a fresh campaign to tackle illegal hare coursing.
They say the activity - where dogs are set free to chase hares - is becoming more common here, and that some coursers have threatened landowners with violence.
Now police from Suffolk, Cambridgeshire and Lincolnshire have got together to launch Operation Galileo: and they are warning they will get tough with anyone they catch.
Four police forces have teamed up to launch a high profile campaign against hare coursing.
Cambridgeshire, Lincolnshire, Norfolk and Suffolk forces officially launched Operation Galileo today.
