Child killer Jon Venables has been jailed for three years and four months after admitting surfing the dark web for extreme child abuse images and possessing a "sickening" paedophile manual.
Venables, who kidnapped, tortured and murdered toddler James Bulger 25 years ago, was charged after police found more than a thousand indecent images on his computer in November last year.
It was the second time he had been caught with such images and when he was arrested he told police he was plagued by "stupid urges."
Sentencing him on Wednesday at the Old Bailey, Justice Edis said the latest images were "vile" and "heartbreaking," adding that many showed abuse of young boys like James.
He added that, given Venables' background, it was significant that a number of the images were of crimes against young boys.
The judge described the manual as a "vile document" and told Venables that by consuming these "products of barbarous evil," he caused abuse to happen.
James's mother Denise Fergus and father Ralph Bulger were in court for the hearing.
Earlier the judge declined a request to delay sentencing so Bulger could make a victim impact statement, saying: "I know the impact on these two people of what happened when their child was killed.
"I know already how it must be for them when that tragic event is once more brought into the public domain into court and so on because of the offending of one of the killers."
Venables, who was released on licence in 2001 after serving eight years for the murder of two-year-old James, had pleaded guilty to four new charges.
He admitted having 392 category A images, 148 category B images and 630 category C images as well as having a paedophile manual on or before November 17 last year.
