A letter in which Moors Murderer Ian Brady claims to have killed four more people has been published for the first time, on the Daily Telegraph website.
In the seven page letter, written by Brady in 1989, he said he killed two men in his native Glasgow and then killed a man and a woman in Manchester, where he and his partner Myra Hindley abducted and murdered five children in the 1960s.
But Greater Manchester Police said the claims have been thoroughly investigated and found to be "completely unsubstantiated".
Terry Kilbride, whose brother John was killed by Ian Brady in 1963, said the Moors murderer should remain in hospital and be "kept alive as long as possible" because he knows where victim Keith Bennett is buried.
He said: "He should remain there, that's my honest opinion, he should remain at Ashworth.
"He knows what he's doing, he's a very clever person up there, which he will be, he's had plenty of time to learn hasn't he, he's got a law degree, he's learned German and all this, that and the other.
"But he should stay where he is, that's my honest opinion on it. I don't believe he's going to kill himself, that's just a ploy, just another wind-up.
"I think to be honest he should go back to hospital, I think that's where he belongs, in the hospital, and keep him alive as long as possible because it's only him that knows where Keith Bennett is."
Alan West, the step-father of Lesley Ann Downey, one of the victims of Ian Brady, believes it's right he not be allowed to transfer to prison.
West told ITV News Brady is "the worst of the worst".
Ashworth Hospital medical director Dr David Fearnley denied that Ashworth Hospital had "gone to war" with Ian Brady.
He said: "I don't think anything could be further from the truth."
"The mental health tribunal process is a legal process, but it's extremely important that we provide the best evidence we can to allow the tribunal to make the best decision it can because of the serious consequences."
Asked if the public platform of the tribunal may have exacerbated Brady's illness, Dr Fearnley said: "I think the difficulty with an individual such as Ian Brady is that he has a complex mental disorder and for many years has been able to publicise his concerns.
"However, we see this as part of an overall problem which our experts are looking into and will continue to provide expert care."
Ashworth Hospital medical director Dr David Fearnley welcomed the decision from Ian Brady's mental health tribunal to keep him in the high security hospital.
He said: "We appreciate the time and effort the mental health tribunal has taken in considering this quite extraordinary case and its judgement that Ian Brady will remain on at Ashworth Hospital is consistent with the advice our expert clinicians gave.
"This means Ian Brady will remain in the right place to receive the right treatment by the right people.
"Ashworth Hospital has been subjected to in-depth scrutiny over the past two weeks and the public has been able to see at first hand the quality of care that we offer to all our patients.
"Ian Brady suffers from a severe personality disorder and a chronic severe mental illness.
"However, he still requires high quality specialist care".
Ian Brady's mental health tribunal concluded:
The Tribunal has concluded that Mr Ian Stewart Brady continues to suffer from a mental disorder which is of a nature and degree which makes it appropriate for him to continue to receive medical treatment and that it is necessary for his health and safety and for the protection of other persons that he should receive such treatment in hospital and that appropriate medical treatment is available for him.
The reasons for the Tribunal's decision will be announced in due course.

Brady told his mental health tribunal he is not psychotic or insane and should be allowed to serve the rest of his whole life term in prison.
Officials at the high security Ashworth Hospital argue that he is also a paranoid schizophrenic who still shows signs of chronic psychosis.
