A group called Urban Fox Hunters has posted a video on the internet that appears to show a fox being clubbed to death in an east London park.
The video, which the group claims was shot in Victoria Park, appears to show the fox being drugged and chased before it is beaten with a cricket bat.
A spokesman for animal welfare group League Against Cruel Sports said: "If the video's true then we're horrified people are behaving in this way."
Whether this is an example of sporting cruelty conducted by sick vigilantes or humane pest extermination conducted by responsible citizens appears to be the question at issue. The court of public opinion - as well as an actual court - may well determine the answer.
And I suspect the participants have let themselves down by using a cricket bat. The use of something more joylessly functional would have been appropriate.
