The room has pink wallpaper dotted with cartoon characters. On a bed covered with the kind of soft, fluffy duvet more often found in a young girl's bedroom, sits the forlorn figure of Ye Mexia. Her black hair is tied with pink ribbons and she is dressed in woollen tights, shorts and the kind of soft jacket often worn by young girls.
It is hard to guess her age because she is heavily made-up to hide her fatigue. Her clothes indicate she could be nine or 10, but in fact she is in her 20s.
Ms Ye, who says she is from Shanghai, is the human face of people trafficking that was exposed a few weeks ago after a bust by Spanish police of a brothel racket in the Leganes area of Madrid.
One of 19 mainland women arrested in a major operation in Spain in recent months, Ms Ye told investigators that she was forced to work in cramped conditions and cater for men fantasising about having sex with children.
Police who busted the prostitution rackets said they were being run by triad bosses in Spain who were making about Euro14 million (HK$145 million) a year out of the sex trade.
A specialised police unit arrested the 14 leaders of six gangs who were running about 100 mainland women in a tightly controlled series of brothels across the country.
They kept one step ahead of the police for months by changing the brothels every few weeks, sometimes working in hotels or operating a 'home delivery' service where girls would visit clients' homes. Although only 19 of the women were detained by authorities on immigration charges, they all had one thing in common: they were sex slaves, 'owned' by the gangs and working to repay the price of a ticket to the west from the mainland.
