The Government is facing growing calls to disclose more details about the return to prison of one of James Bulger's killers.
Jon Venables, who is now 27, was taken back into custody last week for breaching the conditions of his release.
But little is known about the reasons why and ministers have refused to provide further details.
Even James's mother, Denise Fergus, has not been told why Venables was back behind bars.
Justice Secretary Jack Straw defended the decision, saying the secrecy was in the public interest.
But the detective who led the investigation into the killing said the public should be told.
Detective Albert Kirby told Sky News: "I think the statement that came out last night actually raises more questions than it answers.
"It would help to clarify and put this to rest once and for all if the public did have some indication of what it is he has done.
"Not where he is or details like that but the reason why his probation has been revoked and he is back inside."
Mark Thomas, editor of the Liverpool Daily Post, who wrote the definitive book about the Bulger case backed the public right to know what happened.
