London - Abby sat in the back of the car twisting her fingers nervously. She pushed her bangs out of her eyes but her hands quickly returned to her lap, clasped tightly together. Her chipped pink nail polish served as a reminder that these are the hands of a schoolgirl - a schoolgirl living a nightmare.
For the last two years, Abby had been repeatedly raped by men far older than she is. She was 13 years old the first time it happened.
"It went on from 7 o'clock, when it started getting dark, to roughly 3 or 4 o'clock in the morning," she said.
Abby smiled, but the smile never reached her pretty hazel eyes. On this drizzly Friday afternoon, she showed us the places in the northern English city of Leeds her rapists had taken her: fast-food restaurants, hotels, alleyways.
We pulled up outside a children's playground. Abby was brought here by someone she thought was her friend and then was raped by 20 different men. It was the same park she played in with her sisters. She said being here again made her feel sick.
Abby isn't alone. The British government estimates that as many as 10,000 children in the U.K. may be victims of sexual exploitation by gangs, and fears the number could be much higher.
