The BBC has found that children as young as 10 are being groomed in Romania, to be trafficked to the UK.
Once they arrive as teenagers, they're kept captive and pimped out for sex.
With police struggling to stop this brutal trade, BBC correspondent Jean Mackenzie has spent two years travelling between Romania and the UK. She uncovers why this industry is thriving, as she meets the girls being bought and sold.
