A man who bit, punch and beat his victim before brutally raping her while she was still in "great pain" has died in hospital.

Evil Wayne Mansfield died while serving a 17-year-sentence for a brutal rape that forced his terrified victim to testify against him.

Durham Crown Court heard Mansfield has "sadistic tendencies" during the attack, while police branded him "manipulative and controlling."

The monster was locked up in 2013 before being moved to notorious HMP Frankland in County Durham in 2014, a prison known as Monster Mansion.

Monster Mansion is home to some of Britain's most evil killers, terrorists and sex offenders with inmates including Ian Huntley and Sean Mercer.

A Prisons and Probation Ombudsman revealed Mansfield died of pneumonia he caught in hospital while recovering from cancer.

The cancer battle, which led to Masnfield’s pancreas being removed, is believed to have left him too frail to fight off pneumonia.

In statement, the Ombudsman said Mansfield was "underweight, was frail, had diabetes and poor mobility," but had refused health care, ChronicleLive reported.

Back in September, he was admitted to hospital because of an abnormal blood test result and he was treated for malnutrition while chained to bed.

Prison staff discovered Mansfield unresponsive on November 5 and he was traded for low blood sugar before being taken to hospital.

Days later, the rapist died in hospital from what the doctor said was "community-acquired pneumonia."

In a report, the doctor said, "the removal of his pancreas after pancreatic cancer and frailty contributed to but did not cause his death."

The prison watchdog noted the use of restraint during his first hospital visit had contributed to "significant swelling and bruising to his wrists."

It was recommended that prison staff regularly review the level of restraints" on prisoners in hospital.

Following Mansfield’s death, HMP Frankland has introduced an action plan having agreed to implement a recommendation made about the use of restraints.
