One of the men convicted of murdering Stephen Lawrence has admitted he was part of the attack on the teenager but refused to name the other killers.
It is the first time since Stephen was murdered in the racist stabbing in April 1993 that one of his killers has publicly admitted being involved.
David Norris was giving evidence via a video link from prison during a public parole hearing in which he is bidding for release on licence.
Stephen's mother, Baroness Doreen Lawrence, says Norris remains a danger to the public and must remain in prison and the justice secretary is also opposing his release.
Stephen, 18, was stabbed by a gang as he waited at bus stop in Eltham, south-east London.
The parole hearing is taking place 13 years after Norris and another man, Gary Dobson, were found guilty of Stephen's murder and handed life sentences at the Old Bailey.
Only Norris and Dobson have ever been brought to justice, with four other suspects never convicted.
Norris elected not to face the camera, with only his back visible on screen at the parole hearing. He could be seen in a black T-shirt, glasses and with greying hair.
Norris said he and his family would be "at risk" if he gave details about the others responsible for Stephen's murder.
Asked if any of the group had a weapon that night, he said: "I am not here to discuss other people, I am here to take responsibility for my part in what happened, my actions."
He said: "In an ideal world I could tell them the whole truth of my part and others.
"I can't give them everything they wish as it would pose a risk to me and my family."
Describing the night of Stephen's murder, Norris said he had been on a date and saw a group of people that he knew.
Norris said he was ready for violence "at the drop of a hat", and that there was a "gang mentality" among the group.
Witness evidence in the case records that an extreme racist slur was used towards Stephen and his friend Duwayne Brooks just before the gang attacked.
