A total of 13 suspects were arrested in Oxford on Thursday by police investigating claims 24 vulnerable girls under 16 were groomed for rape.
A driver who struck a police officer and then fled the scene has been jailed for seven years.
Stephen John Fahri, 30, of no fixed abode, was sentenced at Maidstone Crown Court after pleading guilty to grievous bodily harm with intent to resist arrest and dangerous driving.
The incident occurred in Southborough on Dec 9 last year. The officer stood in front of the car, which drove at him, the policeman ending up on the bonnet.
The officer was not seriously injured and hopes to return to duty soon.
