They have cheated justice for nearly 19 years.

But the rest of the Stephen Lawrence killer gang were warned yesterday that they will not get away with murder.

Jailing Gary Dobson and David Norris for the ‘terrible and evil crime which scarred the conscience of the nation’, Mr Justice Treacy dramatically ordered Scotland Yard to hunt down the ‘three or four’ killers still at large.

Police, he declared, should not ‘close the file’ on the case.

His forthright comments were backed by Stephen’s parents, Neville and Doreen, and prompted the Metropolitan Police Commissioner

Significantly, police have already received a number of calls about Stephen’s murder since Tuesday’s convictions.

The trio of men long suspected of joining Dobson and Norris in the ‘racist and thuggish’ South London lynching in April 1993 are brothers Neil and Jamie Acourt and Luke Knight.

Their names were handed to police within days of Stephen’s murder and all five were named by the Daily Mail as killers in 1997 and challenged to sue if the newspaper was wrong. They never did.

Outside the Old Bailey Mr Lawrence said he hoped Dobson and Norris would ‘give up the rest of the people’ involved and effectively handed officers a 12-month deadline to make fresh progress.

‘One of my greatest hopes is that these people have now realised that they have been found out, and they are now going to go and lie down in their beds and think that they were the ones who were responsible for the death of my son,’ he said. ‘And they are going to give up the rest of the people so that I (can) come out here again in a year’s time and talk to you people again.’

Stephen’s mother Doreen told the Mail: ‘There is no shred of doubt in my mind that all five are guilty. After Stephen’s death we had people we don’t know leaving messages and giving us their names. We would have had no idea about these young men, who they were and where they lived, but we were getting these messages about their behaviour; the way they cleaned knives in front of their windows, attacks on other people.

‘So with that combination of things, and then seeing the police surveillance video where it’s clear the hatred they have for individual races, you think, no, it has to be them.’

Met chief Bernard Hogan-Howe insisted detectives would go after the remaining suspects. He urged people to come forward with information which might prompt new charges.

he new phase of the marathon Lawrence investigation is expected to focus on the Acourt brothers and Knight, who were in hiding last night after apparently fleeing their homes. It is also likely to include a renewed attempt to identify a possible sixth member of the gang.

The comments of Mr Justice Treacy, in a packed but silent courtroom at the Old Bailey, will terrify the Acourts and Knight, who have so far dodged justice over Stephen’s murder. After jailing Dobson and Norris and praising the detective who helped put them behind bars, the judge said: ‘At least a measure of justice has been achieved at last.

‘However, the convictions of Gary Dobson and David Norris will not, I hope, close the file on this murder. On the evidence before the court, there are still three or four other killers of Stephen Lawrence at large.

‘Just as advances in science have brought two people to justice, I hope the Metropolitan Police will be alert to future lines of inquiry, not only based on developments in science but perhaps also information from those who have been silent so far, wherever they may be.’

Police plan to meet next week to assess where the case stands.

Dobson, 36, and Norris, 35, were convicted on Tuesday of the racist murder of Stephen. Dobson, who is already serving a five-year sentence for drug-dealing, was sentenced to at least 15 years and two months.

Norris was given a minimum of 14 years and three months for what the judge described as a ‘terrible and evil crime’.

In court, Mr Justice Treacy called forward Detective Chief Inspector Clive Driscoll, who has been the senior officer in the case for a number of years.

He told him that the public inquiry into the circumstances surrounding Stephen’s death had ‘shamed and humbled’ the Met, but praised the hard work done in recent years.

The evidence in the trial could not prove who wielded the knife, but he said that whoever used it had done so with Dobson and Norris’s ‘knowledge and approval’.

Neither of them had shown ‘the slightest regret or remorse’ since the murder and they had both lied to the court. At Scotland Yard, Mr Hogan-Howe said his officers would continue their inquiry into Stephen’s murder, adding: ‘We can make a difference in this case still.

‘The other people involved in the murder of Stephen Lawrence should not rest easily in their beds. We are still investigating this case.

‘If anybody out there has any more information or any evidence, even after all this time, please tell us then we’ll do the rest. All we need is help.’
