A 17-year-old and four men arrested in connection with kidnaps and sexual assaults on children have been released on bail.
It is alleged the group assaulted four young girls, three aged 14 and one aged 15, in four separate incidents in July.
It is believed they travelled to the Newark area and took the girls to addresses in Leicestershire, where the assaults allegedly took place.
The suspects were all arrested on suspicion of child abduction on Wednesday following a series of raids at properties in Leicester.
Two were also arrested on suspicion of serious sexual assault.
The 17-year-old boy and four men, two aged 18, one aged 20 and one aged 23, have been released on bail pending further enquiries.
