Martin Lomas, Deputy Chief Inspector of Prisons said Mr Dvorzac had been in handcuffs for almost five hours and was still wearing them when he died:
The use of restraints in this case was shocking. All senses of humanity seem to have been lost.
Clearly the performance by the contractor running Harmondsworth has been below the high standard expected. It is for the Home Office to decide if the contact should be removed.
Harmondsworth now needs to concentrate on the needs of the most vulnerable men it holds at the centre.
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."
