Although two individuals are serving a life sentence in connection with this murder, we have always known there were other people involved in the attack ...
It is hoped this appeal will assist with our inquiries.
We believe there were people in the area that night who may have seen something. Not the murder itself necessarily but events or individuals leading up to the event.
I am taking this opportunity to appeal directly to those people to come forward and speak to us. You may think you won't remember something from so long ago, but we would still implore you to come forward.
Police will launch a fresh appeal for witnesses to the murder of Stephen Lawrence 20 years since the attack on Crimewatch tonight.
Stephen was stabbed to death by a group of up to six white youths in an unprovoked racist attack as he waited at a bus stop in Eltham, south-east London in 1993.
Gary Dobson and David Norris were convicted of his murder last year and jailed for life after a forensic review of the case found significant new scientific evidence on clothing seized from their homes. But the case remains open.
Police hope that by walking viewers through the events again they may persuade witnesses to come forward.
