Two men have been arrested as part of a police investigation into illegal sheep butchery in Northamptonshire.
A 23-year-old man and a 35-year-old man from Birmingham were detained in the early hours, police said.
Officers responding to a report of suspicious activity in a field near Welford on Sunday October 6.

The two men were arrested on suspicion of theft and criminal damage.
The stopped vehicle was seized by officers and will undergo forensic examination.
