Andrew Jaipaul, 21, was stabbed to death on a housing estate in Holloway, north London, on Sunday 26 June 2011.
He was attacked by a gang of between 12 and 20 young men as he made his way home near Andover House, Andover Road, at 10.23pm.
Andrew, a painter and decorator who lived in Birnam Road, Holloway, suffered a total of 25 stab wounds and was pronounced dead at the scene.
Detectives arrested a total of 18 men during the investigation. Eight suspects were charged with murder: Tommy McInerny, 20 [1/11/91], of Pilgrims Way, Upper Holloway, Jojo Mafwa, 18 [13/5/94], of St Margaret's Avenue, Tottenham, a 15-year-old boy from Upper Holloway, Allan Kalema, 19 [23/09/93], of Stevenage, Hertfordshire, Tirrell Ball-Thomas, 18 [18/7/94], of Colthurst Crescent, Finsbury Park, Orvill Sterling, 18, from Green Street, Enfield, and a 17 year-old man from Tottenham.
They went on trial at the Old Bailey on May 16, 2013. The prosecution case is that Andrew was attacked by members of the 'Busy Blocks' gang at the height of a feud with a rival group.
Prosecutor Zoe Johnson QC said Andrew had been 'in the wrong place at the wrong time'.
She added: 'He found himself the victim of escalating attacks between rival gangs in north London.
'Andrew Jaipaul was minding his own business when, out of nowhere, a large, armed gang came across him, decided to attack him, chased him down and brutally murdered him near a children's play area.'
The trial continues.
