Jamaican-born Baroness Doreen Lawrence has called for British police to launch a new investigation into the 1993 murder of her son, following a convict’s admission that he took part in the attack, according to a BBC report.

The murder of 18-year-old Stephen Lawrence at a bus stop in Eltham, United Kingdom (UK) by a gang, in what was widely thought to be a racially motivated attack, had rocked the British nation.

Gary Dobson and David Norris were convicted in 2012, but neither ever admitted to being involved in the murder.

At least six men were suspected of being involved in Lawrence’s brutal stabbing, though the other four were never convicted.

The report says with Norris’ admission that he punched but did not stab Lawrence, comes the first time a suspect has publicly admitted to being involved in the murder.

His admission was shown during a livestreamed parole hearing this week.

Baroness Lawrence, who was born in Clarendon, Jamaica and sits in the UK House of Lords, told reporters on Wednesday that the police should urgently investigate the new admission.

She added that Norris owes her the truth and the Metropolitan Police owes her justice, the BBC said.

The report cited reluctance from Norris to name his accomplices in the murder, out of what he describes as fear for his and his family’s safety.

The report indicated that the Metropolitan Police says a review of the murder investigation commenced in 2013, and is to assess if any opportunities exist to bring more of the young man’s killers to justice.

A parole board is to decide whether Norris can be released from prison safely, with at least one psychiatrist telling the hearing that he is not fit for release, citing racist behaviour in prison. However, another psychiatrist requested by the convict said that he could be released safely.
