The Global Slavery Index 2018 estimates that on any given day there were nearly 8 million people living in modern slavery in India. The GSI 2018 reports an emerging trend in northeast India where organised trafficking syndicates operate along the open and unmanned international borders, duping or coercing young girls seeking employment outside their local area in to forced sexual exploitation. Many women and girls are lured with the promise of a good job but then forced in to sex work, with a 'conditioning' period involving violence, threats, debt bondage and rape.  Sharifa was trafficked in to prostitution by her husband.

An orphan who was tricked into leaving her village in northern Nigeria in 1998, Joy Ubi-Ubi fashions the turning-point from freedom to slavery as the moment when she drank blood during a voodoo ritual. Afterwards, once Joy was in Europe, her captors said this ritual meant the “juju” would kill her if she tried to escape. As Joy explains, she was thereby “forced to do the work” of a prostitute. She was enslaved for three years in the deprived Bijlmer district of Amsterdam—home to many West African immigrants. But the narrative also includes a parallel turning-point from slavery to freedom: the moment when Joy was asked to drink something again: a liquid that would make her bleed, and miscarry. This time, she refused to take the drink. Not wanting to abort her pregnancy, she made the decision to escape, then was helped by a West African Pentecostal minister who operates mission houses in Amsterdam. This use of native West African voodoo is a common feature of the slave experience for Nigerian women held in Western Europe (of whom there are around 10,000). The women and girls undergo an initiation ritual before leaving their country: for Joy this included the marking of her face and hands, and laying hands on a “juju” (statue), as well as drinking blood. They are often made to swear to the gods that they will work hard for their employers, and will never mention their real names, run away, or contact the police. Captors threaten the women with punishment by the gods for any disobedience, and warn that any attempt to escape will awaken a curse on their families. Once in Europe they are drugged, then resold. Held in brothels, they have sex with customers but are not paid: Joy notes that all money changed hands before the clients reached her room. Any pregnancies are aborted.
