Chief Constable Sir Peter Fahy said: Greater Manchester Police has previously launched an investigation into complaints of abuse at Knowl View.
A number of new victims have recently come forward and we are looking to identify new suspects.
As a result of the publication of the book, and the subsequent press coverage, we are now reviewing whether there is evidence to justify us opening a criminal investigation into any previous allegations which were not pursued.
We note the announcement of the inquiry by the independent QC, announced by Rochdale Borough Council. We will liaise with the QC to make sure that this inquiry does not compromise the abuse investigation and to receive any material relating to our criminal investigation.
Our review will be carried out by experienced officers from our Serious Crime Division. It is in the nature of sex abuse investigations that it takes considerable time to gather evidence from people who have been very damaged from the experience and clearly this is more difficult when matters occurred many years ago.
We are now appealing for anyone who has information in relation that can assist either investigation – the complaints of historic abuse or a possible cover up – to contact Greater Manchester Police.
