South Yorkshire Police 'failure to follow up allegations'
South Yorkshire Police had evidence that hundreds of girls were facing sexual exploitation in Sheffield in recent years, but failed to investigate many of the allegations.
A former officer has told the BBC the force ignored evidence that girls as young as 12 were being raped and physically assaulted.
It is also claimed he received direct orders to abandon his inquiry into child abuse.
Michael Buchanan has this exclusive report.
