A DANGEROUS prisoner has been treated at Sunderland Royal Hospital.
The man, who is serving a sentence at HMP Frankland near Durham, arrived at the hospital under police escort on Thursday morning.
He received medical treatment and is believed to have spent some time on a ward, under police guard.
Officers from Durham Police escorted him back to the high-security prison near Brasside, home to about 700 of the country’s most dangerous prisoners.
The man, who has not been named, is a category A offender.
This status is given to those whose escape would be highly dangerous to the public or national security.
He may be behind bars for crimes such as murder, attempted murder, manslaughter, rape, indecent assault, firearms offences, terrorism or importing class A drugs.
Inmates of Frankland, which has a Dangerous and Severe Personality Disorder Unit, include child killer Ian Huntley.
However, a spokeswoman from Her Majesty’s Prison Service denied it was the 38-year-old former school caretaker.
A Durham police spokesman said: “We can confirm officers from Durham Constabulary escorted a category A prisoner from Frankland Prison to Sunderland Royal for medical treatment.
“The escort then returned him to Frankland later in the day after his treatment had been completed.”
