New reports into Jimmy Savile say allegations of abuse at four different institutions in the North West are credible but lack evidence.
A joint police and NSPCC report had previously described Savile as a prolific, predatory sex offender whose abuse started in Manchester in 1955.
An investigation into allegations that Jimmy Saville carried out abuse at hospitals in the North West has found no evidence to support claims that Saville attacked patients at two hospitals in Greater Manchester.
The allegations related to incidents at Birch HIll and the Rochdale Childrens' Hospitals.
But a series of reports published today have also concluded there is no "reason to disbelieve" two women who claim they were attacked by him while at Ashworth Hospital.
A man who suffered abuse at the hands of Jimmy Savile has spoken to ITV Granada Reports about his experience.
The man, whose identity has been protected, says the television presenter picked him out on a visit to the Broome House children's home in Manchester in the 1970s.
He, and a leading victims' solicitor, have both raised concerns about a deadline for victims of historical sexual abuse to make claims for damages, which expires next month.

A former children's home, under investigation over allegations Jimmy Savile abused its residents, was filmed for an ITV documentary in the decade the allegations date back to.
Broome House, in Manchester's Didsbury, featured in "This Is England" in the 1960s.
The now closed institution has been named as one of three children's homes under investigation in the city.
A lawyer representing 140 victims of disgraced television presenter Jimmy Savile welcomes announcement that 20 children's homes and schools are to be investigated.
They include 3 former children's homes in Manchester.
"We welcome any investigation that will uncover further how widespread Savile's abuse was. It is important that we know exactly when, where and how this predatory paedophile committed his horrific crimes.
"Mr Gove's announcement comes in the same week that he said in the Commons Government would investigate the possibility of introducing mandatory reporting for heads of institutions where children and the vulnerable are cared for.
"It is frankly shocking that people in authority who become aware of abuse are still not committing a crime if they decide to cover it up."
A spokesperson for Manchester City Council said:
"We take all allegations of abuse extremely seriously and will do everything we can to investigate as thoroughly as possible in accordance with the process and within the timescales set down by the Department For Education."
Three Manchester children's homes are being investigated in the inquiry into abuse carried out by the disgraced television presenter Jimmy Savile.
The Sarah Laski Home, Broome House, which are both closed and another unnamed children's home are part of 20 homes and schools where it's claimed Savile abused children. The allegations date back to the 1960s, 1970s and 1980s.
Education Secretary Michael Gove has confirmed local authorities and other relevant institutions have been asked to further investigate the claims.
