Three men are in custody after CCTV footage captured a group of dogs entering a private garden and killing a fox.
Police were called shortly after 3.30pm on Monday after receiving reports that the dogs had gone into a garden at an address in the village of Hingham, Norfolk.
Footage of the incident was shared online by wildlife campaigners, the Hunt Saboteurs Association.
The three suspects were arrested on Friday following enquiries, police said.
They have been taken to Wymondham Police Investigation Centre in Norfolk for questioning.
Two men in their 20s from the town of Swaffham have been arrested on suspicion of hunting a wild mammal with dogs, criminal damage and having a dog dangerously out of control.
A third man in his 60s from the Beccles area has been arrested on suspicion of hunting a wild mammal with dogs and having a dog dangerously out of control.
Additional enquiries are being conducted after a separate incident earlier this month in the village of Tittleshall, Norfolk Police said.
