NZ woman tells of sex-slave nightmare

A New Zealand woman has revealed how an exciting Facebook invitation turned into a nightmare.

Mary Elizabeth Jones, 39, has told the New Zealand Herald how she was forced into prostitution after being duped by a Facebook invitation to join a martial arts school.

A martial arts enthusiast, Ms Jones later answered a message from the group inviting her to an intense training camp in the Philippines in October.

"They were meant to be world class and I thought this was a chance for me to learn from the best," Ms Jones told the Herald.

She was instead robbed of her belongings and thrown into a bug-infested room after she was picked up in Iloilo City Airport by a man who claimed he was the group's leader.

Jones was made to have sex with up to nine men a day, with each reportedly paying 5000 pesos (NZ$140).

"I felt utterly disgusted, and I was treated like a piece of meat," she told the Herald.

"It was meant to be a trip of a lifetime but it has destroyed my whole life instead."

Ms Jones was punished with beatings when she attempted to escape.

She was dumped on the streets of Manila after torment and starvation left her too weak to stand.

"I hate myself immensely and feel so dirty. I wish I could have just died in the Philippines rather than go on living like this," says Ms Jones.

Five months after her ordeal, Ms Jones is recovering in a boarding house in Mangere and wants to warn others.

The Philippines is listed as a source country for human trafficking, according to the latest Trafficking in Person Report by the US Department of State.

"Hundreds of victims are subjected to forced prostitution each day in well-known and highly visible business establishments that cater to both domestic and foreign demand for commercial sex acts," the report says.
