Shocking video of a yob throwing a stone at a PONY

The footage appears to show a boy picking up a stone or pebble and throwing it hard at the white pony only a few metres away behind a fence. The poor animal, called Robin, can be seen jumping in pain at the alleged unprovoked attack at Bourton Vale Equestrian Centre in Gloucestershire. The incident was recoded by an apparent friend of the attacker and put on Facebook. It soon resulted in the video spreading across multiple platforms and people have reacted with anger and horror at the clip.
