Three men from Market Harborough have been released on bail after being arrested following a high speed car chase across three counties.
They were detained on Thursday afternoon after the Subaru Legacy they were driving was detained at a travellers' site near Market Harborough.
The chase started in Lincolnshire and went through Leicestershire into Northamptonshire and involved officers from all three forces.
The police helicopter based at Husbands Bosworth also assisted in the chase.
The men were suspected of taking part in illegal hare coursing and had failed to stop for the police.
The arrests took place just over the county boundary at the Justin Park site in Northamptonshire south of Market Harborough.
A police spokesman said: "Three men aged 39, 29 and 27 all from Market Harborough were arrested for failing to stop for police and on suspicion of hare coursing.
"They have been released on bail pending further investigations."
Police are appealing to anyone who believes they may have seen the vehicle involved, a silver Subaru Legacy estate, between 8am and 2pm on February 12.
PC Martin Green said: "We are urging people who believe they saw the Subaru car yesterday to call Lincolnshire police on 101 with any information they have."
