Margaret Oliver, a former detective and family liaison officer for Greater Manchester Police, has said no one wanted to listen to her when she worked on grooming cases in Rochdale.
She said she worked on an operation in 2004 which was almost identical to the Rotherham cases, which were exposed in a report earlier this week.
A report published on Tuesday said at least 1,400 Rotherham children were sexually abused between 1997 and 2013.
