Princess, 43, trafficked from Nigeria into prostitution in Italy

We saw people return from Europe rich. A woman said she would give me work in a Nigerian restaurant in Italy. When I arrived I was told I had to pay back a £40,000 debt before I could leave. They said they would kill me if I didn’t work as a prostitute. The work was so dangerous. I was stabbed twice. I managed to leave, and now I work to help other women escape. These traffickers take everything from you – all that makes you human. I say to the women I help: ‘Let us not rest until we have brought them all to justice.’
