Dallas police arrested a 13-year-old middle school student Saturday and charged her with luring young girls into prostitution.

It was in Club Metropolis that police say the 13-year-old girl lured other girls, enticing the teens with the promise of money, and even forcing some of them to dance and sell their bodies for sex.

Teen prostitution is a big problem.

"It's a really horrendous affair," explained Lt. Chess Williams, with the Dallas Police Dept.

Dallas police say there are hundreds of teenage prostitutes on the streets because there is a big demand.

Recently, they found a 12-year-old girl dancing naked at a nightclub.

"I can't believe that a 13, 14, 15-year-old child knowingly injects herself into a world of prostitution," said Lt. Williams.

But it happened, and the 13-year-old in this case may have talked another school friend into prostitution.

Police won't say what school, but they're not surprised.

"One of the remarkable things we learned through all of this is there is a tremendous amount of money in all this, so a huge demand for young girls in prostitution world," stated Lt. Williams.

Police say the young girls aren't acting alone.

They say some of the same people who are pimping out the adult prostitutes are the ones exploiting young girls.

This 13-year-old and others like her may be runaways, whose childhoods were stolen for profit.
