A Nigerian man and his wife who have been holding 9 Nigerian women in sexual slavery have been busted in Moscow, Russia.

Some of them were brought to Russia during the 2018 FIFA World Cup, when entry procedures at the border were eased for tourists.

They reportedly go through witchcraft ceremony where they are put under a curse if they do not pay back their madam.

The woman, a former prostitute was also tricked into coming to Russia.

The women believe the couple paid around $50,000 to get them to Moscow, and they work for years by having sex with thousands of clients to pay off their debt.

Activists from both Russia and the United States, committed to eliminating sex trafficking around the world, found the women and tried to convince them to leave.

The women finally agreed to leave, but the price for their ‘freedom’ turned out to be too high.

Deportation would likely mean the couple won’t be prosecuted
