Oxford Street Foot Locker stabbing: Gang violence blamed
Deep seated "bad blood" was the background to the fatal stabbing of a teenager in London's Oxford Street during the Boxing Day sales last year, a prosecutor has alleged.
Seydou Diarrassouba, 18, of Mitcham, south-west London, was killed on 26 December in the Foot Locker sports shop, near Bond Street Tube station.
A post-mortem examination found he died from a single stab wound.
Jermaine Joseph, 23, and Thulani Khumalo, 20, deny murder.
BBC home affairs correspondent Tom Symonds reported from the court that Mr Diarrassouba received a 10cm wound from a knife which broke due to the force of the blow.
The stabbing was the result of "gang violence" on the street, said Mark Heywood QC, prosecuting.
He said: "The grievance was evidently a deep and powerful one.
"It led almost instantly to ugly, brutish violence in broad daylight in a packed street on the busiest shopping day of the year.
"You may think that was one of the days and places people could go in peace."
Mr Joseph, from Tottenham, north London, told police he acted in self-defence.
Mr Khumalo, from Finsbury Park, north London, has denied involvement in the stabbing.
The trial continues at the Old Bailey.
