When Michael Tyrrell's oldest daughter Ash visited her dying father in hospital and saw him handcuffed and chained to a prison guard, she was so shocked that she took photographs. Tyrrell, who was almost halfway through a 29-year sentence for drug smuggling, had throat cancer and pneumonia. He had lost five stone in weight and barely had the strength to move. He had not been a troublesome prisoner: after 13 years of good behaviour, he was due to be released in 2015. The handcuffs were taken off a few hours before he died the following day.
