TWO prisoners have been found guilty of killing a fellow inmate by carrying out plans to attack him at Peterborough prison.

Brian Haynes, 33, formerly of St Ives, died of a heart attack after being assaulted in his cell at HMP Peterborough on September 11 last year.

On Tuesday (December 22) following a trial at Norwich Crown Court, Sebastian Waller, 26, of Moorland Court, Skaters Way, Peterborough, and Shane Farrington, 25, of HMP Peterborough, were found guilty of manslaughter.

Paul Jefford, 24, of Wellington Street, Peterborough, had already pleaded guilty to manslaughter.

Three men were found not guilty. They were Sammy Lindsay, 22, of Bainton Green Road, Bainton, Stamford; Gary Stretch, 24, of Badgeney Road, March and Dale Maddison, 44, of Deacon's Lane, Ely.

The court had previously heard of a plot to give Mr Haynes a violent warning.

Mr Haynes had been serving a four-year sentence for drug dealing and causing grievous bodily harm by attacking a stranger with a baseball bat in Cambridge in December 2007.

The court heard resentment had grown over Mr Haynes' reputation for dealing drugs and tobacco.

The injuries Mr Haynes suffered were not serious enough to kill him but an underlying health condition caused him to have a heart attack. His body was discovered by a prison officer that evening during lock-up.

Detective Superintendent Tony Ixer, who led the police investigation, said: "The attack which resulted in Mr Haynes' death was a joint venture designed to give him a violent warning. It was pre-planned and those convicted are all responsible in some way for his death.

"I hope this result allows Mr Haynes' family to move on and put this terrible ordeal behind them knowing that justice has been done. Our thoughts are with them.
