Investigation into prisoner's hospital death closed
NHSNo further action will be taken against a prison officer who was arrested on suspicion of manslaughter after a prisoner died.
Derek Macdonald was taken from HMP Lancaster Farms to Royal Lancaster Infirmary after he "had become unwell and agitated" at about 17:20 GMT on 25 January, Lancashire Police said.
The 35-year-old was accompanied by prison officers before Lancashire Police arrived at the hospital to support them and restrained him.
A few minutes later Macdonald's medical condition worsened and he stopped breathing. He was given CPR, but was pronounced dead at 18:30.
A prison officer in his 30s was arrested on 31 January.
He was released under investigation but has now been told he will face no further action following an investigation into Macdonald's death.
The incident was referred to the Independent Office for Police Conduct, who carried out their own independent investigation into the role of the police during the incident.
They concluded that no police officer was at fault and closed their investigation.
