The murder of Stephen Lawrence shook the nation back in 1993 as it revealed the extent of the UK's problem with racism, and highlighted racist attitudes within the police.
On April 22, 18-year-old Stephen was waiting at a bus stop trying to go home with a friend when he was surrounded by six assailants who stabbed him repeatedly before running off, his friend Duwayne Brooks said.
His injuries were so catastrophic that he died before making it to the hospital 20 minutes after the attack, and in the days that followed Stephen's murder, several residents came forward to provide the names of suspects.
