THE monster who murdered his pregnant girlfriend and three children is already being threatened with jailhouse justice, a source says.
Damien Bendall has been behind bars less than 48 hours since admitting to the quadruple killing but is said to be receiving round-the-clock protection.
That's because inmates have already warned the 32-year-old: “You won’t be seeing Christmas".
On Wednesday Bendall was handed a for killing wee Lacey, 11, her brother John, 13, their pregnant mum , 35, and pal Connie Gent, 11, at their home in Killamarsh, Derbys, last year.
The horrific details of their deaths were also revealed - including how their "skulls were smashed in" with a claw hammer and that the monster raped Lacey.
After the killings, Bendall took young John's Xbox to trade for drugs and walked to the shop for tobacco, before calling police and saying "I've murdered four people".

The chilling moments were captured on CCTV and police body cams.
But other lags - and criminals on the outside - are now threatening to kill him, a Ministry of Justice source said.
It understood Bendall is caged at top security Wakefield Prison in West Yorkshire.
The lock-up is dubbed Monster Mansion because of the numbers of high-profile murderers and sex offenders housed there.

The source told The Sun Online: “The prisoner is on round-the-clock watch in segregation for his own safety.
“He is being located in a secure unit for his own protection. Feelings are running very high both inside and outside the prison and he has received threats.
“At times he has been kicking off in custody.”
The source added: “A risk assessment was made and a decision taken as it was felt that someone could hurt him or he could hurt himself.
“He is being treated as a person at risk. A lot of outrage is being expressed by inmates. Child killers are loathed inside.”
Bendall has been handed the most severe available in the UK justice system - which is only dealt to the most twisted criminals.
And, following his sentencing, a criminologist told of the three chilling clues that revealed his sick mind.
A report has also found that Bendall was left “free to kill” after “blunders” by the Probation Service.
Meanwhile, a source said that the monster styled himself as a football thug and neo-Nazi to menace others but it was all a front.
