A young gunman known as Scarface has been jailed for life for the murder of a promising teenage footballer. Richard Harrison-Allen, 20, shot Etem Celebi dead in November 2007 as he tried to flee the scene in the Smalley Close estate, Stoke Newington, north London. Gang member Harrison-Allen, from Hackney, east London, who was convicted of the teenager's murder earlier this month, was sentenced to a minimum of 26 years at St Albans Crown Court. He sat motionless as sentence was passed.
