Chilling moment balaclava clad yob pulls out gun to 'assassinate' teen in London

This is the terrifying moment a yob pulled out a handgun before 'assassinating' a 15-year-old boy in broad daylight during a 'family fun day' in west London. Rene Graham was gunned down while surrounded by parents and children at Emslie Horniman's Pleasance open space - also known as 'Teletubbies Park' - in Ladbroke Grove last July. The shooting took place at an annual pre-Notting Hill Carnival event and allegedly came amid a violent postcode war between rival gangs.
