Three men from Rushden and Wellingborough were among a group fined after being convicted of hare coursing in Cambridgeshire.
Police officers attended an incident on farmland in Sawtry on December 13 last year, after receiving reports of six men trespassing and hare coursing on the land.
A police helicopter was scrambled to help catch the group and all six were charged. A dog, two vehicles and cash were also seized.
Charlie Doherty, 25, of Newton Road, Rushden, Francis Doherty, 37, and John-Brian Lee Senior, 43, both of Gipsy Lane, Irchester, and James Doran, 35, from Essex, were all charged with two counts of daytime trespass by five or more in pursuit of game.
Each received a £300 fine, ordered to pay £300 in costs and forfeit the vehicles after being found guilty at trial.
Two youths were also given cautions.
