The National Crime Agency (NCA) said most of the potential suspects were Asian men, while the vast majority of victims were young British girls.
The NCA launched a major investigation into the scandal after a damning report by Professor Alex Jay last year, revealed that as many as 1,400 children had been raped, trafficked and groomed by mainly Asian gangs in the South Yorkshire town between 1997 and 2013.
Following the revelations South Yorkshire police, which was criticised for its handling of abuse allegations, asked the NCA to intervene and the agency launched Operation Stovewood.
