Moors Murderer Ian Brady may have revealed information about where one of his victims, 12-year-old Keith Bennett, is buried, detectives believe.
Greater Manchester Police said officers think Brady gave details to a long-term visitor to his psychiatric hospital.
Police said a woman has been arrested in south Wales on suspicion of preventing the lawful burial of a body.
Detectives are now examining a number of documents but concede it could be a "ruse" by Brady.
Brady and Myra Hindley murdered five children between 1963 and 1965. Keith's is the only body never found.
