A moped rider who allegedly killed a young man in London's upmarket Knightsbridge and was then helped to flee abroad within nine hours may never face justice, a court has heard.
Yousef Razak is accused of fatally stabbing 25-year-old Blue Stevens in front of his girlfriend in Seville Street on the evening of July 9.
Within hours, Mr Razak had boarded a ferry to France and travelled on to the Middle East, where he remains wanted, jurors were told.
