TV adventurer Bear Grylls is at the centre of an animal cruelty row as it emerged pigs were specially shipped to an island to be slaughtered by contestants on his reality show for "entertainment".
Many viewers were distressed by a scene in The Island which saw a sleeping pig captured and killed on camera. It was the third pig slaughtered on the show in two weeks.
In an earlier episode, two piglets were killed for food after they fell ill.
Channel 4 admitted that producers put the domestic animals on the island for the contestants to hunt and kill.
Animal rights campaigners claim pigs are not afraid of people so do not run away when threatened.
