Two men have been convicted of the racist murder of teenager Stephen Lawrence, 18 years after he was stabbed to death near a south London bus stop.

Gary Dobson and David Norris were found guilty by an Old Bailey jury after a trial based on forensic evidence.

Scientists found a tiny bloodstain on Dobson's jacket that could only have come from Mr Lawrence.

They also found a single hair belonging to the teenager on Norris's jeans. Sentencing will be on Wednesday.

In an exclusive interview with reporters, Stephen's mother Doreen Lawrence said: "I don't forgive the boys who killed Stephen. They don't think they have done anything wrong.

"They took away Stephen's life and there is nothing in their behaviour or anything to show they regret what their actions have done and the pain it has caused us as a family."

Duwayne Brooks, Stephen's best friend who had been with him on the night of the murder, tweeted: "Some justice at last".

The original failed investigation into the murder led to the Metropolitan Police being branded as institutionally racist.

Stephen Lawrence was 18 when he was stabbed to death near a bus stop in Eltham, south London, in April 1993.

By that time, there had already been a catalogue of police errors and two failed prosecutions, one brought by Stephen's parents.

But in a four-year-long cold case review, a fresh team of forensic scientists uncovered microscopic evidence linking two of the five men to the murder - evidence that the police had held all along.

The material - bloodstains, clothing fibres and a single hair belonging to the teenager - were recovered from the clothes of the suspects which had been seized in 1993.

Scientists recovered the material using advanced techniques which were not available to the original case scientists.

Dobson, 36, and Norris, 35, denied the murder. They said their clothing had been contaminated as police mixed up evidence over the years. Detectives spent months establishing the movements and handling of the exhibits since 1993 - and the jury were told that contamination was implausible.

Dobson was jailed for five years in 2010 for drugs trafficking. He is among a small number of men to have been tried twice for the same crime after the Court of Appeal quashed his 1996 acquittal for the murder.

Norris was convicted in 2002 of a separate allegation of racially threatening behaviour.

In mitigation, ahead of sentencing on Wednesday, counsel for Dobson said there was no evidence he had been the leader or prime motivator of the group that attacked the teenager.
