France Tries 23 in Alleged Nigerian Sex Slave Ring Lisa Bryant PARIS - Nearly two dozen people went on trial Wednesday in the French city of Lyon for what activists say is an all-too-common reality in Europe: allegations of forced prostitution involving migrant women. The 23 defendants face up to 10 years in prison if found guilty of a slew of charges, ranging from money laundering to human slavery. They are suspected of running a sex-trafficking ring that turned Nigerian women hoping for better lives in Europe into sexual slaves. Those on trial include a Nigerian pastor, accused of being the ring leader, and a woman suspected of recruiting Nigerian women as prostitutes in Lyon and two other French cities. She is on the run and being tried in absentia. .
