Two Nigerians in Spain have been arrested in connection to a prostitution ring as they were identified to have used voodoo to force their victims into commercial sex in several Spanish cities.

The man and woman arrested were picked up on the filed warrant issued by another Nigerian female in Oslo, Norway.

The two suspects' home was raided and they found out items suspected to be charms and fake documents. The couple had promised unsuspecting victims a job and good welfare, only to travel to Spain and forced to become prostitutes.

The Nigerian who lodged the complain claim the woman had used her in Spain, France and Norway in the past since 2011.

The couple would perform rites of initiation, which has included animal sacrifice, and forbid the victims unto utmost secrecy or die if the truth ever comes out
