Pattinson said the prisoner had been secured in his own cell within the van.
“There are no indications the death is suspicious,” he said.
“Our thoughts are with those impacted by this man’s death. Staff and prisoners are being provided with support.”
Police have been notified and have contacted the man’s next of kin.
“All deaths in custody are referred to the Coroner for investigation and determination of cause of death,” Pattinson said.
“An investigation by the independent Corrections Inspectorate will also be carried out.”
Police confirmed they attended a sudden death at Mt Eden Corrections Facility today, and inquiries will be carried out on behalf of the Coroner.
