Assignment tells the story of a young street trader from Lagos who ended up at the heart of an organ harvesting plot involving a senior Nigerian politician and a hospital in the UK. The young man was tested, trafficked and tricked into a plot to remove his kidney, to donate to the daughter of one of Nigeria’s most powerful politicians. As Mark Lobel discovers, the criminal trial and conviction is the first of its kind in the UK – and has led to police investigating more potential cases.
