An 84-year-old detainee died while in still restraints after being taken to hospital from Harmondsworth Detention Centre, a report has revealed. The Canadian man, Alois Dvorzac, had been declared by doctors as being unfit for detention because he had Alzheimer's disease.
The Prisons' Inspector said it was one of a number of cases where ''a sense of humanity was lost''.
A statement from private contractor GEO said: "Detainees are not routinely handcuffed when taken out of the centre.
"However, where there is a documented risk of absconding, handcuffs may be used, balanced against a number of factors, including their age.
"Managers have to use discretion to take difficult decisions and we have issued them with additional guidance."
An investigation has been launched into the death of a detainee at an immigration removal centre (IRC).
The detainee died at Harmondsworth IRC in west London yesterday.
A UK Border Agency spokesman said: "This death is being investigated so it would be inappropriate to comment at this stage.
"We will work with the prisons and probation ombudsman during the investigation."
Harmondsworth IRC, near Heathrow Airport, is a purpose-built, long-term centre which holds up to 615 detainees pending their removal from the UK.
