A man has been arrested on suspicion of affray following disorder at a Boxing Day hunt, police said.
Anti-hunt protesters and members of the Avon Vale Hunt clashed in the village of Lacock in Wiltshire on the morning of December 27.
Footage posted on social media showed punches being thrown and someone being hit with a placard.
In a statement, Wiltshire Police said a man in his 30s had been arrested on suspicion of affray and released under investigation while inquiries continue.
“We have received a number of calls from members of the public with information in relation to the incident,” a force spokesman said.
“We would urge anyone who was present who may have information which could help our inquiries to get in touch, as well as anyone who may have their own footage of the incident.”
The Office of the Wiltshire Police and Crime Commissioner said it was assessing complaints about police conduct at the hunt.
“We are aware of an incident between Avon Vale Hunt members and hunt protesters which took place in Lacock on December 27,” a spokeswoman said.
“Any correspondence received about the conduct of Wiltshire Police relating to this incident is in the process of being assessed by the OPCC complaints team. This ensures investigative independence and oversight.
“All correspondence will be handled in a fair, open and honest way and will be handled as efficiently as possible, with correspondents being advised of the outcome.
“Should a legally eligible complaint be made then the official complaints process will be followed.”
