An specialist operation to crack down on hare coursing in Lincolnshire has recorded more than a thousand incidents in the last year. The illegal sport can generate thousands of pounds in betting money, but for the farmers it's a blight on their land.
Kate Hemingway went out on patrol with Lincolnshire police as part of Operation Galileo.
Police in Lincolnshire say they are still catching hare coursers on a daily basis.
Lincolnshire Police launched their special crackdown on hare coursing, 'Operation Galileo', last September and say they are bringing more offenders to justice.
There have been 550 prosecutions since September 2012, and 1200 reported cases over the last year.
One recent incident resulted in around £30,000 worth of betting on dogs for the offenders.
The illegal sport, which involves dogs like lurchers chasing hares to kill them, can mean big money for those behind it.
But the police face a common problem - the coursers will say they have been given permission to be on the land to catch rabbits, and witnesses are often reluctant to give evidence. Sergeant Dave Robinson of Lincolnshire Police has been talking to Kate Hemingway.
Police say to date 21 men have been prosecuted for crimes relating to illegal hare coursing in Lincolnshire. A specialist police team have been in operation in the area for one month now.
In that time they have caught offenders from as far as the West Midlands and Wales who have travelled to the area to hunt. They've also recovered 5 vehicles, rescued five dogs and seized mobile phones.
