These crimes were committed in the locality where I worked before retiring. Young women that were under my supervision would get caught up with some of these pimps two or three years before this came to light. Offenders with a prostitution and drugs history were encouraged to take new girls along to flats in the town centre. They complained to each other about these men and the local police were informed. No formal complaints were made but much intelligence shared. I was told that these men despised white girls, and I guess this is where this issue has arisen, as they would have been questioned about their choice of victim and this could be reframed in court as a race issue i.e. the asian men being targeted and unfairly penalised by police and the criminal justice system because of their attitudes to white women. However, it doesn't matter whether they did or not - they knew how vulnerable many of the young women were, and used them to recruit younger girls.
The English Collective of Prostitutes are active in this area, and issue guidelines to young women to help them keep safe. Unfotunately, young women coming out of prison are vulnerable and willing to bring along other victims with the promise of gifts of money, drugs, alcohol and mobile phones. There are plenty more pimps still operating, but fewer women being released from prison to that area, as the hostel has now been moved to another county. Taxi drivers are significant in these offences - they pick up prostitutes and homeless girls and offer them free lifts or a bed for the night from the station and town centre.
