Does this put a different light on it?
Julian Worcester, the deputy director of children's services, told The Guardian, which obtained the leaked report: 'They were being trafficked and there has been organised movement through the facility.'
But he told the Mail that the unit - labelled a children's home by The Guardian - was actually an assessment unit where officials determine whether migrants who may be in their teens are children or not.
Most residents were between 16 and 20 years old, but economic migrants often claim to be under 18 so they will not be detained by the Border Agency, said Mr Worcester.
The leaked document highlighted a particular influx of Chinese youngsters who had paid people smugglers up to �15,000 a head to bring them to Britain, he said.
