Teenager was murdered in racially motivated attack in London in 1993
Stephen is a sequel to the network’s landmark 1999 programme, The Murder of Stephen Lawrence, and will focus on the investigation into the 18-year-old’s killing.
Mr Lawrence’s death marked a watershed moment in cultural life and race relations, although campaigners say the UK has a long way to go.
Since 1993, wide-ranging changes have been made to policing and the law thanks to the tireless efforts of Lawrence’s parents, Baroness Doreen Lawrence and Neville Lawrence.
Who was Stephen Lawrence?
Mr Lawrence was born in Greenwich and raised in Plumstead, southeast London, to Jamaican parents who had emigrated to the UK in the 1960s.
He was the eldest of three children and attended Blackheath Bluecoat School, where he excelled at sport and had been preparing for his A-levels.
At school, Lawrence studied technology, physics and English language and had aspirations of becoming an architect.
