Greater Manchester Police say their ongoing investigation into historic sex abuse at Chetham's School of Music is a "significant" inquiry due to the number of potential offenders and the volume of complaints received.
Detective Chief Inspector Jamie Daniels said many of the women have been persuaded to report attacks by Francis Andrade, who committed suicide after giving evidence at the trial of her former abuser Michael Brewer.
This is a significant inquiry in terms of potential number of offenders and number of victims.
We are supporting each and every person who has come forward and made a complaint to us as best we can and I must credit them all for having the courage to face demons that have been haunting them for many, many years.
I want to reassure the public that I am absolutely committed to getting justice for these women, many of whom have been spurred on by the bravery shown by Frances Andrade in the case against former teacher Michael Brewer.
