The victim of a fatal stabbing inside Oceana threw the first punch, a court has heard.

Jamie Sanderson, 20, died of a single stab wound to the heart after being stabbed in the Kingston nightclub in the early hours of October 25 last year.

Levan Greenfield, 22, Ashley Milne, 23, both of Peckham, and Brandon Francis, 19, of West Dulwich, and Benjamin Onwuma, 20, of Walworth, all deny murdering him.

At the Old Bailey today prosecutor Crispin Aylett QC said: "Some time after 3 o'clock in the morning Jamie Sanderson got into an argument with one or more of the defendants.

"There was some pushing and shoving.

"The victim, Jamie Sanderson, it is fair to say, was more to blame. It was Jamie Sanderson who appears to have thrown the first punch.

"The evidence for this comes from a number of sources."

He said the stabbing took place in a crowded corridor where different witnesses, some who were affected by drinking, heard and saw different things.

But he said: "There is evidence from a number of CCTV cameras including one that covers the corridor in which the fatal incident took place.

"At one point it appears Francis had Jamie Sanderson in a headlock.

"Onwuma and Greenfield were either side of Francis. Milne was not far behind and was heading towards them."

Victim 'kept fighting' even after being stabbed

The jury heard that witnesses had heard someone say 'pass the nank' which they were told was slang for a knife.

Mr Aylett said: "Even though he had been stabbed Jamie Sanderson carried on fighting. It may be that he was unaware that he had been fatally stabbed.

"The victim was bungled into a lavatory for his own protection."

But the court heard that even though Mr Sanderson's friend pointed out he had been stabbed, he was keen to keep fighting.

He soon collapsed and died on his way to hospital from the single stab wound to his heart.

The Old Bailey was told that Mr Milne had stayed inside the club but a friend of Mr Sanderson pointed him out to door staff.

Mr Aylett said: "It was noted this man had blood on his sleeves."

Mr Milne was kept back by door staff and arrested by police when they arrived. The other defendants were arrested in the weeks that followed.

The court heard that Mr Milne had told officers that as he had been leaving the club there had been a commotion and he noticed someone on the floor.

Mr Aylett said that Mr Milne claimed he had tripped over the victim and that is how he came to have Mr Sanderson's blood on his sleeve.

Mr Onwuma gave no comment to all the questions asked by the police, the jury was told.

Mr Aylett said: "Jamie Sanderson was stabbed only once so of the four defendants only one could have been the actual stabber."

Jurors heard that different witnesses recognised different defendants as the only one who carried out the attack.

But Mr Aylett said the murder had taken place as a 'joint enterprise' in which each of the defendants played a part.

He said: "The attack on Jamie Sanderson was one that was carried out by the group, each of them knowing that one of them was carrying a knife, one that might  be used to stab someone."

Clubber's first night out without an electronic tag

In August, Jamie Sanderson was convicted of a sexual assault and as part of his sentence had an electric tag for two months, the court heard.

Mr Aylett said: "When Jamie went to Oceana on Wednesday 24th October it was only two days after the tag had been removed.

"It was in fact his first night out and it seems unsurprising that he was in rather high spirits."

The court heard that Mr Milne arrived through the Woowoo bar at 9.40pm that night and did not go through a knife arch or get patted down by door staff.

The other defendants arrived at the venue at about 1.15am with friends who had booked tickets for the student night online, the Old Bailey jury was told.

There were about 90 different cameras covering the inside and outside of the premises at the time, and even more now, Mr Aylett said.

He said Wednesday night was a student nightwith a foam party in the main auditorium with as many as 1,700 people inside the club. There were also a number of people waiting to get in.

The court heard Jamie Sanderson arrived with friends just after 1am.

Three of the four defendants arrived afterwards and went through a knife arch.

The jury was told that Mr Sanderson had bumped into an old friend with whom he had attended a Northolt school.

He bought Mr Sanderson a Jagerbomb drink.

Mr Aylett told the jury this friend said Mr Sanderson had told him he was looking forward to the future after removing his electronic tag.

The trial continues.
