A MAN who died in HMP Peterborough has been named by police as 33-year-old Brian Haynes, from Huntingdon.

Meanwhile eight inmates have been arrested by police as part of the murder inquiry.

A post-mortem examination was carried out on Mr Haynes' body at Peterborough District Hospital but police say further tests need to be carried out to establish the cause of death.

Detectives have been quizzing prisoners since the victim died after being found in his cell.

Today it was revealed that there will also be an independent investigation into the incident by the Prisons and Probation Ombudsman.

The murder inquiry began after a wing officer found the 33-year-old man from Cambridgeshire slumped unconscious at around 8pm on Thursday night.

Paramedics and police arrived at the prison in Saville Road, Westwood, but despite attempts to revive him, he was declared dead at 9pm.

Kalyx, which runs the prison, released a statement which said: "It is with great sadness that we announce the death in custody of a 33-year-old Cambridgeshire man during the evening of Thursday, September 11.

"At approximately 8pm, one of the wing officers failed to get a response from the man, who was in his cell.

"Prison staff, nurses, and paramedics attempted to resuscitate him, but without success.

"Cambridgeshire police is investigating the circumstances surrounding the death.

"There will also be an independent investigation conducted by the Prisons and Probation Ombudsman.

Prison director Mike Conway expressed his condolences.

He said: "We are unable to release any further details until it has been confirmed that next of kin have been notified.

"Our thoughts and sympathy go to his family and friends at this difficult and tragic time."
