An 18-year-old Spalding man is one of two people arrested so far after a spate of criminality around Ely last weekend.
An investigation was launched following multiple reports of hare coursing, criminal damage and dangerous driving in various parts of the Fens around Ely, Littleport and Chatteris.
The incidents, which were reported to have involved up to 70 people in around 25 vehicles, prompted a public apology from Cambridge Chief Constable Nick Dean after the police response on the day was widely condemned.
A force-led investigation was launched subsequently.
The 18-year-old and a 26-year-old man from Grantham were arrested on Friday on suspicion of violent disorder and attending a hare coursing event.
Both have now been bailed to return to Thorpe Wood Police Station, Peterborough, at a later date.
They have the following bail conditions:
Not to be in possession of, be in control of, or be in the company of any dog on private land without the owner’s written permission.
When in possession of, in control of, or in the company of any dog, said dog must be on a lead.
Not to be in a vehicle with any dog, while outside of a five-mile radius of your home address, unless for a pre-arranged veterinary appointment.
Not to be in possession of a catapult or shot, such as a ball bearing, and/or an air weapon or any part of an air weapon.
They must not drive or be conveyed in a mechanically propelled vehicle onto private fields of agriculture field belonging to another person without written permission presentable to an officer.
They must not use any public spaces, footpaths, bridleways or other such like areas belonging to the local authority or another unspecified person with the intention to hare course.
They must not shout at, swear at or intimidate any persons in any of the following 12 counties: Lincolnshire, Cambridgeshire, Norfolk, Leicestershire, Northamptonshire, Nottinghamshire, Suffol, Essex, Bedfordshire, Hertfordshire, Kent and Derbyshire.
Police have also seized four vehicles, three in Grantham and one in Essex, as well as hare coursing equipment.
The incidents took place in Ely, Fordham, Litleport, Welney, Chatteris, Manea, Wimblington and Doddington.
One local farmer said he saw 13 vehicles and around 70 people on his farm.
At a public meeting held immediately afterwards, Chief Constable Nick Dean apologised to local residents for the ‘failure of police’ to deal with issues on the day.
