She has been classed as a vulnerable inmate.
Murderer Emma Tustin has been put into prison isolation after becoming a "massive target".
The 32-year-old was found guilty of murdering 6-year-old Arthur Labinjo-Hughes earlier this month. Tustin is expected to serve a minimum of 29 years in prison.
She is serving her sentence at Peterborough jail but has now been declared a vulnerable inmate.
The killer has no contact with other prisoners.
She eats, washes, and exercises with only prison guards around her.
A source told The Sun, "Every effort is being made to protect her from attack. Like it or not, prison officers have a duty to keep order and the rule of law inside."
"In her case, they’re gritting their teeth to do it but she’s a massive target," they revealed.
"It’s only a matter of time before someone takes a chance to do her in," they revealed.
Tustin violently attacked little Arthur when she was minding him.
The 6-year-old suffered a catastrophic blow to the head when she attacked him.
Arthur died from a severe brain injury at the mere age of 6.
His father Thomas Hughes was found guilty of manslaughter. He was sentenced to 21 years in prison.
During their trial, the court was told that Arthur was subjected to the medical definition of child torture.
Both Hughes and Tustin starved the young boy and laced his meals with salt.
Tustin forced Arthur to sleep on the floor in the living room.
6-year-old Arthur was isolated from the family. He was also forced to stand alone in the hallway for up to 14 hours a day and was punished if he tried to sit down.
What the young boy went through is unbearable to even think about. Many believe that Tustin's sentence was not severe enough for what she did to her stepson.
