Jon Venables threatened to the children of prison staff when he didn’t get his own way, it was claimed.
The James Bulger killer was said to throw tantrums and taunt prison staff while he was incarcerated at a secure children’s home for young offenders.
A former inmate said Venables was also given special treatment by staff at the unit after he was jailed for the two-year-old’s murder.
The unnamed former lag branded Venables ‘one sick c***’.

‘He was one sick b*****d, running around saying “I’ll kill your kids, I’ve done it before” if he did not get what he wanted,’ he told The Star.
‘He would say all sorts of sick stuff and kick off to the staff.
‘He was twisted. He will never stop.’
The ex-prisoner even claimed Venables was spoiled as he was given up to £23 a week in spending money.

It comes after another former inmate, James Peak, revealed how he attacked James Bulger’s killer for bragging about brutally murdering the little boy.
The 39-year-old, of Birmingham, served time at the same Merseyside secure unit as Venables back in 1994.
Heap was 14 when he claims he punched an 11-year-old Venables ‘in his little face’ for gloating about his and Robert Thompson’s crime that shocked the nation.
He told the Sunday Mirror the child killer said abducting and murdering the toddler was ‘easy…just like going to the shop’.
The labourer added: ‘The look on Venables’ face as he laughed about the murder will stay with me forever.
‘He’s got this mad face when he grins, the most evil little face you’ve ever seen.
‘That was enough for me – I didn’t want to hear any more of that.’
An 11-year-old Venables allegedly gloated about taking James from the New Strand Shopping Centre in Bootle, Merseyside in February 1993, saying: ‘I done it easy’.
It came as the Daily Star reported that Venables claimed he was ‘possessed by the devil’ when he murdered James.
He is said to have made the boast to prison guards while awaiting sentencing for child porn offences.
Meanwhile, Heap’s revelation comes after Venables was sent back to prison for being in possession of child pornography for the second time since his original release on licence in 2001.
The Old Bailey heard the killer, who was given a new identity by the Home Office, hid his laptop with the disturbing images behind his bed.
A document found on his computer detailed instructions on ‘how to have sex with little girls…safely’.
The content is supposed to have been based on the experience of the author with his own two daughters.
Heap also claims Venables revelled in how horrific the details of his crime were and refused to show any remorse.
He is believed to have lied to other youngsters at the the unit, saying he was serving time for burglary.
Heap also revealed how a young Venables would threaten to ‘go after’ other inmates and their families on his release and was attacked by other inmates.

Venables spent eight years at the unit but Heap claims he had it easy, with a pool table, games room and his own Game Boy at his disposal.
When asked to do things by staff he would refuse, telling them to ‘F*** off’.
On the 25th anniversary of James Bulger’s death two documentaries re-examined Thompson and Venables crimes.
During James Bulger: A Mother’s Story with Trevor McDonald on ITV, his mother Denise Fergus said her son’s killers have ‘never been punished properly’.
She told the broadcaster: ‘I did say that if they weren’t punished properly, then they would go on to re-offend — and that’s exactly what’s happened.
‘I’ve never had justice for James’.
