But the new conditions now mean he has more money to spend in the canteen, gets more time out of his cell and has access to workshops, the library and gym.
A source told The Sun: “It is outrageous that they have raised him to standard.
“They are basically bribing him to behave — by saying we’ll give you a telly and you can keep it if you don’t attack anyone.
“It makes his life a lot more comfortable and also means he can spend more on phone credit.
“He will get a Freeview TV with about 25 channels and the DVD player, though his access to films will be limited.
“Rudakubana is cock-a-hoop about the change but I doubt the officer who had liquid chucked in his face will be.”
The Ministry of Justice declined to comment.
The incident in May, where the 19-year-old is alleged to have thrown scalding water on a guard, is still under investigation.
The prison officer was taken to hospital as a precautionary measure, did not require further treatment and was discharged later that evening, it is understood.
Rudakubana was jailed for a minimum of 52 years in January for the murders of three girls and attempted murders of eight other children, class instructor Leanne Lucas and businessman John Hayes.
He murdered Alice da Silva Aguiar, nine, Bebe King, six, and Elsie Dot Stancombe, seven, and injured 10 others during the attack at the Taylor Swift-themed workshop on July 29 last year.
