Dawn raids took place involving 100 police officers across Oxford to arrest perpetrators of child sex abuse.
The raids took place in eight properties across Oxford this morning and eight men were arrested.
Police said alleged offences included rape, sexual grooming and indecent assault on girls from 1999 to 2007.
This stand-alone operation comes just months after the Oxford Serious Case Review was published which found more than 300 young people had been sexually exploited and groomed by gangs across Oxfordshire for the past 15 years.
Oxfordshire MEP and Long term anti-trafficking and child sexual exploitation campaigner, Catherine Bearder, commented:
“It is clear we have a real problem here in Oxford but it is good to see Thames Valley Police taking action in light of the Serious Case Review.
"This comes only a month since it was reported by victims of the Bullfinch gang that this is still happening in Oxford. I hope this is partly a result of hearing and believing these girls.
“It is important that victims are being supported – this is a major step in the right direction and I would urge any further victims of exploitation to come forward in the knowledge they will be believed.
“These girls have been through the most horrendous experiences – many will have been raped night after night and moved around against their will and some will have been brought to the UK under false pretences of a good job.
“Once again we see child sex abuse going on right under our noses. This proves the need for us all to open our eyes to the signs of human trafficking, recognise it and report it."
