Two men have denied the murder of a sixth-form student, who was stabbed to death as he walked with a friend in Brixton. Kwame Ofosu-Asare, who was 17, was on his way to the friend's relative's house when they were chased and attacked. Kwame died from stab wounds. The friend was unhurt.
Nelson Idiabeta, 18, of no fixed address, and Nathaniel Okusanya, 19, from Lambeth, deny murder.
