The grooming and sexual exploitation of vulnerable girls by gangs of men has been widely reported.
There have been convictions across the country, including high profile cases in Telford and Derby.
But there is a group of victims suffering in silence. Campaigners say girls from the Asian community are easy targets, because they're less likely to report it.
In this special report, Balvinder Sidhu has been to meet a girl who says she was abused and, when she told her parents, was forced to leave the country.
In part two, she looks into the ethnicity of those who commit the crimes, following the suggestion that British Pakistani men are disproportionately involved.
