NO further action will be taken against the Llangennech mental health advocate of Moors murderer Ian Brady.
Jackie Powell, 49, of Llangennech, was arrested in August and a warrant carried out at her Brynhyfryd estate address, after claims she made on a Channel 4 documentary about a letter that revealed the final resting place of the only one of Brady's victims not to be found.
She was released on bail, but Greater Manchester Police have today said no further action would be taken against a woman they arrested in August in South Wales.
Ms Powell, who has been Brady's mental health advocate since 1999, made the headlines last year after being arrested on suspicion of preventing the burial of a body.
Police were searching for a letter, believed to contain details of the final resting place of 12-year-old Keith Bennett, after Ms Powell claimed Brady had handed it to her to give to the mother of Keith, Winnie Johnson — but only after his death.
Martin Bottomley, head of investigative review of Greater Manchester Police's Major and Cold Case Crime Unit, said: "As soon as we were made aware of the existence of this alleged letter, we made exhaustive attempts to obtain it to establish whether or not its contents would assist us in finding Keith's body.
"That resulted in the warrants we carried out in the South Wales area and at Ashworth Hospital in August 2012.
"However, despite seizing numerous documents and a search of Brady's cell, no such letter has been recovered."
He said the failure to find the letter did not prove or disprove its existence, adding: "It might have been destroyed, it might be hidden elsewhere, it may be in someone else's possession, or it may simply never have existed in the first place and this has been yet more mindgames by Brady.
"What I can say for certain is that we have not recovered the letter itself nor any credible information that would help us find Keith.
"As a result, we have liaised with the Crown Prosecution Service (CPS) who have concluded there is no realistic prospect of any criminal conviction and therefore no further action will be taken against the woman we arrested."
