A row between two men on a Bishopsworth street resulted in one being fatally stabbed through his eye, a court heard.

Bradley Payne grabbed a kitchen knife when he went to confront 43-year-old John Derrick, Bristol Crown Court was told yesterday.

The jury heard Mr Derrick said he would fight without weapons but Payne produced the blade and "savagely" attacked him, stabbing him in the stomach and head, with the fatal wound going into his brain.

Payne, aged 32, of Witch Hazel Road, Hartcliffe, denies murder in July last year.

He also denies making a threat to kill and unlawfully wounding Aaron Bennington relating to a separate incident the previous month.

Ian Pringle QC, prosecuting, told the jury that on Saturday, July 12 last year, Payne visited his parents' home just outside Bristol.

Mr Pringle said around 6pm that day Mr Derrick visited the home of Payne's partner Samantha – also called Payne but no relation – at Innox Gardens in Withywood.

Mr Pringle told the court: "It would appear Samantha Payne didn't wish him there and she summoned the help of Bradley Payne. We know it because we have some texts which will show that that's what she wanted."

Mr Pringle told the court Payne, with the help of his father, forcibly ejected Mr Derrick from the premises and Payne's father called the police.

Mr Pringle said that, angered, Payne decided to sort things out and arming himself with a kitchen knife, took a BMX bike and went out to find Mr Derrick.

He said: "In essence the defendant and John Derrick confronted one another.

"They exchanged insults and John Derrick shouted 'I'll fight you, but no weapons'.

"The defendant dismounted, he approached John Derrick and shouted: 'I'm going to kill you!'

"He took the knife out from behind his back and swung it with his right hand.

"He hit John Derrick in the stomach and almost immediately he swung it again and stabbed him in his eye.

"John Derrick collapsed almost immediately and the defendant left the scene."

The jury heard a large number of people went to Mr Derrick's aid and police and an ambulance were called.

A post mortem later concluded Mr Derrick had been stabbed through his left eye and into his brain, rupturing a main artery which supplied the brain and causing massive bleeding.

Payne was arrested when he walked into Broadbury Road police station and when asked if he was a witness to the incident said: "No, it was me," the court heard.

In interview he accepted he had left Innox Gardens with a knife but he claimed he had not intended to inflict the fatal wound but Mr Derrick had walked onto his knife – a claim which the prosecution regards as "nonsense".

It is alleged that about a month before Payne visited the home of Aaron Bennington, produced some kind of implement and stabbed him on his left cheek, forehead and in the stomach, after accusing him of touching his partner Samantha improperly.

Mr Pringle told the court Mr Bennington was scared after the attack and did not report it, but found the courage to do so when John Derrick was killed.

The case continues at Bristol Crown Court.
