Tobore Ovuorie, Nigeria
Tobore Ovuorie's investigations into the trade in fake mosquito nets and fake yellow fever vaccination cards already won awards before she even embarked on her biggest feat to date: going undercover inside Nigeria's human trafficking mafia.
The story, exposing how criminal syndicates benefit from tough migration restrictions and from the criminalisation of sex work, made headlines all over the world and earned Ovuorie speaking slots at several investigative journalism conferences.
It also came at great cost to Ovuorie, who was physically and mentally abused during her undercover time with criminals.
Recovering, she now spends more time doing internet-based research and speaking about her experiences, which have informed police investigations in Nigeria and questions in the European parliament.
"Though I would do it differently if I were to do the story again, and I realise that no story is worth your life, I still think that it was and is necessary to report on the risks faced by women in sex work. They still face daily abuse as a result of the criminalisation of their trade."
