At total of 21 men are being prosecuted in connection with illegal hare coursing in Lincolnshire.
Officers involved with Operation Galileo, which is running during the typical coursing season from September until March, have attended numerous incidents and stopped people who have travelled to Lincolnshire from all over the country to engage in this activity.
The men are all being prosecuted for offences committed in Lincolnshire under both the Game Act and the Hunting Act.
Five vehicles have been impounded, five dogs have been recovered using animal welfare legislation, and various leads, collars and mobile phones have also been seized.
Offenders have travelled from as far as the West Midlands and North Wales.
Feedback from some of those involved is that awareness of the dedicated team of officers is spreading, with some who would have travelled here to offend now staying away from the county.
Those who are still taking the risk appear to be settling bets outside the county rather than risk having large sums of money seized from them by the police.
Force-wide wildlife and rural crime officer Nick Willey said: "If anyone sees suspected hare coursers they should try to note specific details, preferably vehicle registration numbers.
"If only make/model/colour details and direction of travel are obtained, this can be useful in tracking the route of hare coursers across the county and may even assist in taking retrospective action against subsequently identified offenders.
"Details of numbers of people involved and what they are wearing, as well as numbers of dogs, can also be used to build an intelligence picture to help direct the police response."
