Video: Steven Lawrence killer David Norris questioned

Footage has emerged of Stephen Lawrence murderer David Norris consistently refusing to comment throughout an interview with police.

During the footage filmed in September 2010 and recently released by the Metropolitan Police, detectives quiz Norris, who was 16 at the time of the murder, on the status of a single hair that forensic scientists had found on Norris's jeans.

Whilst police question the suspect, an unknown officer says: “The finding of that hair would intend to suggest, David, that you were at the scene of Stephen Lawrence’s murder and you were almost certainly involved in his death. What do you say to that?”

He then answers: “No comment.”

Norris even declines to comment on a crucial question: “Is there any account that you can give for me right now that I can go away and investigate that can prove you are innocent?”

“No comment,” Norris replies again.

The detective then warns Norris that if he suddenly comes up with an explanation in court as to how the hair got there, the jury could infer he was lying as he didn’t give any explanation during the interview stage.

Despite the warnings, the hard-faced Norris declines to comment.

The forensic evidence also confirmed a tiny bloodstain on Dobson's jacket that could only have come from Mr Lawrence.

Other videos released by the Metropolitan Police show the pair using violent and racist language, and brandishing knives in their London flat.

Norris, 35, and Gary Dobson, 36, were found guilty of murder on Tuesday by a unanimous jury verdict at the Old Bailey.

The murder had raised searching questions about racism in Britain.
