The story is about a Colombian trade union leader who today begins an unprecedented case against BP in the High Court in London alleging its complicity in his kidnap and torture for 42 days. It is the first time he has spoken about his experiences to international media. BP denies any involvement.

Here are the stories: “Colombian takes BP to court in UK over alleged complicity in kidnap and torture” and “Gilberto Torres survived Colombia’s death squads. Now he wants justice”.

Here is the film about the extraordinary case.
