Attackers armed with knives, baseball bats and a screwdriver killed a young man and injured two others in a horrifying night of Halloween violence, a court was told.

Student Scotty Kouebitra, 22, from Sutton, was with his friends at St George’s Field Park in Selhurst when he was attacked for no obvious reason, jurors were told.

He died after suffering a knife wound to the neck and chest on October 31 last year, the Old Bailey heard.

Prosecutor Louis Mably QC said eight attackers had arrived at the park in two cars, armed with a variety of weapons for a "planned attack."

Mr Mably said: "This was a futile and completely senseless attack."

He said the evidence did not reveal the reason for the killing and whether Mr Kouebitra was simply "in the wrong place at the wrong time."

"There was clearly no justification for this group arriving as they did with weapons and attacking people in the way that they did."

A paramedic called to nearby Gloucester Road found Mr Kouebitra lying on the ground with clothes "soaking with blood" just after 8pm.

Aaron Jackson, 26, of Harrington Road, South Norwood, Jahliel Rose, 21, of no fixed address, Marcus Asemota, 23, of Turpington Close, Bromley, and a 17-year-old, who cannot be identified, deny murder.

They have also pleaded not guilty to wounding Keith Hawker, 28, and Abdil Jamal-Abdilahi, 23, with intent.

When police arrested the 17-year-old, he denied involvement although the victim's blood was found on his clothes, jurors heard.

Rose told police he was out trick or treating with his sister at the time, Mr Mably said.

The trial continues.
