At just seven years old Dzhambulat Khatokhov – Jambik for short – is four foot three inches tall and weighs 16 stone: as much as a baby elephant. He dwarfs his older brother who is twice his age and less than half his weight.

But Jambik is a hero in his home town and an object of fascination in the West. British doctor Ian Campbell travels to the far south of Russia to meet Jambik and his family and uncovers a more disturbing story than he originally imagined.
