21 people, 15 men and 6 women, tall Nigerians, were arrested in the early morning operation for forcing Nigerian women into prostitution after Catalan regional police launched a large-scale raid against human trafficking and sexual exploitation of women in Barcelona, Spain.

The Central Unit against Human Trafficking disclosed that the suspects are part of a criminal organisation, known as “Supreme Eiye Confraternity”, that has forced more than one hundred women into prostitution since the beginning of 2014.

Investigators believe the group may have exploited dozens of women, many of whom were charged large sum of money to be brought to Spain from Africa with the promise of a job and a better life.

Officers are also searching 20 properties in Barcelona, Terrassa, Sabadell and several other Catalan towns and cities.
