The father of James Bulger has said Jon Venables should lose his anonymity after the toddler's killer was arrested again.
Venables, who murdered Bulger in 1993 when he was a teenager, has been arrested again for possesion and distribution of child-abuse images.
Pictures of Venables can not be printed in the media or released to the public, but Ralph Bulger, 51, said he has forfeited this right after the discovery of the images on his computer.
Bulger also said that Venables, now 35, should be given an adult sentence for his involvement in the gruesome murder of his two- year-old-son, James, over two decades ago.
The father criticised the £5 million spent on rehabilitating and keeping Venables and his accomplice, Robert Thompson, anonymous.
He told The Sunday People: "If people saw a photo of him as the adult moster he truly is, they would have a very different perception of the person commiting the crimes, instead of a picture of so-called childhood innocence."
He added that the rehabilitation efforts have failed because Venables re-offended, and therefore he should be stripped of his anonymity.
Bulger added that he believes his son's murderers should be treated no differently to any other child killers.
Venables and Thompson were 10 years old when they tortured and killed two-year-old James in 1993, after abducting him from a shopping centre in Liverpool.
After serving eight years of their sentences they were released with new identities to protect their well-being.
Back in 2010, Venables, then 32, arrested and placed in prison for downloading and distributing more than 100 images of child-abuse.
He was released in 2013 and has now been arrested again.
Bulger believes that justice chiefs must look again at James' murder and admit that it was sexually motivated, in light of Venables' repeated offences.
Bulger added: "You only have to look at the manner in which they tortured my son before killing him to know [the suggestion of a sexual motive] is true, but no-one wanted to hear it or believe it because Thompson and Venables were just 1-. Now they are not."
Both of Bulger's parents criticise the Ministry of Justice for failling to inform them that Venables had been recalled to prision.
James' mother Denise Fergus released a statement saying: "Venables was taken back into custody a week ago, yet I was only informed hours before it hit the press."
She added: "Venables has now proved beyond any doubt what a vile, perverted psychopath he has always been."
