The legal advocate of the Moors murderer Ian Brady has been arrested for allegedly failing to reveal where the body of one of his victims, 12 year old Keith Bennett, is buried.

Brady's legal advocate, Jackie Powell, is being held in custody for questioning, after Greater Manchester Police said they'd recently received information that Brady had finally disclosed the location of the body to one of his 'long-term visitors' at the Ashworth high-security psychiatric hospital where he is held.

The makers of a Channel 4 documentary about Brady alerted the police that Jackie Powell had told them she had received letters from the killer, one of which was for the victim's mother, Winnie Johnson.

Neither Brady nor Hindley, who died aged 60 in 2002, has revealed where Bennett's body was buried, despite repeated pleas from Mrs. Johnson, who is dying of cancer in a hospice.

Bennett was one of five children abducted by Ian Brady and Myra Hindley, who they then tortured, killed and buried on Saddleworth Moor in 1964. The two were taken back to the moor, in the footage seen here, in 1987, to help police find the remains of the missing victims. But after that search only one body, that of 16 year old Pauline Reade, was found.
