An animal rights activist found a dismembered fox tail and a note threatening him to stop protesting hunting on his car windscreen.
The note, left after an animal rights demo in Warwickshire, told Ray Williams to give up abusing hunters online or another fox will die.
Ray had been protesting at Hogwood Farm, which supplies pork to Tesco, on September 30 but when he got back to the car, he found the foxs tail pinned to the windscreen alongside a bloodied envelope.
Inside it, the note read: Every time you abuse a hunter on social media. Another fox will die.
What kind of sad, pathetic little coward would do a thing like that? Ray wrote online after finding the threat.
Well done, yes it did upset us, and yes, it upset a nine-year-old little girl who has been brought up vegan from birth by her amazing mother.
Will it stop us and put us off standing up to animal abusers? Naa thats not gonna happen.
The police logged the incident at the end of last month and undertook forensics analysis.
But unfortunately Warwickshire Police were unable to find any DNA with which to pursue an offender.
Mr Williams said of the incident: Id like to say that myself and every other activist at Hogwood has been treated with fairness, dignity and respect at all times by police liaison officers when attending vigils at Hogwood.
I didnt expect anything to be found and these are the pics of the tail and note that was left.
Id like to add the pathetic attempt by a member of the little willy brigade to put us off attending vigils and trying to stop myself personally from saying horrible things about sad little hunters on social media has failed miserably.
Fox hunters really are pathetic, sad cowards.
Id like to wish every hunt sab a safe and successful weekend, you really are heroes for what you do.
Hogwood Farm came under fire earlier this year after footage of cannibal pigs supposedly eating each other alive hit headlines.
The farm was found to have been surveyed by officials one year previously and had made no breach of animal welfare standards.
Warwickshire Police and Shipston Safer Neighbourhood team have been contacted for comment.
