22 April 1993

Stephen Lawrence is stabbed to death in an unprovoked racist attack by a gang of white youths as he waits at a bus stop in Eltham, south-east London, with his friend Duwayne Brooks. Over the days that follow, police receive several tipoffs. Between them, all sources point to the same suspects: brothers Neil and Jamie Acourt, Gary Dobson, and David Norris.

25-27 April 1993

Police take a statement from the alleged victim of another stabbing by the same suspects, and confirmation of the Acourts’ address from their mother. The other two suspects have been seen outside the same address. Despite having enough grounds to make arrests, police decide instead to begin surveillance of the suspects’ homes. The surveillance team see the suspects walking out of the house carrying bin bags and driving away, but do not pursue them because they do not have a mobile phone.

July 1993

Charges against Neil Acourt and Knight are dropped, following a meeting between the Crown Prosecution Service (CPS) and the senior investigating officer. The CPS says the evidence from Brooks is unreliable, after DS Christopher Crawley makes a statement saying Brooks told him he was unsure of those he picked out. Brooks denies saying this.

December 1993

Southwark coroner Sir Montague Levine halts an inquest into Lawrence’s death after the family’s barrister, Michael Mansfield QC, says there is “dramatic” new evidence, believed to include information identifying three new suspects.

April 1994

The CPS says the new evidence is insufficient to support murder charges.

September 1994

Lawrence’s parents, Neville and Doreen, begin a private prosecution against Neil Acourt, Knight and Dobson. A private prosecution is a standard criminal trial, but not brought by the CPS.

February 1997

The coroner’s inquest resumes. Levine swiftly records a verdict of unlawful killing “in a completely unprovoked racist attack by five youths”. The Lawrence family formally complain to the Police Complaints Authority about the police’s handling of the investigation. On 14 February, the Daily Mail front page displays the names and photographs of the two Acourt brothers, Norris, Knight, and Dobson under the headline: “Murderers”. The paper accuses the men of killing Lawrence and challenges them to sue for libel.

The five suspects appear to give evidence at the public inquiry overseen by MacPherson, having been told they will face prosecution otherwise. The inquiry is adjourned for three hours after police fire CS gas on the protesters. Members of the group Nation of Islam storm the building, saying the inquiry is a sham.

Metropolitan police anti-corruption investigators are given the name of DS John Davidson, who served on the first murder investigation, by his colleague Neil Putnam.

The five suspects are banned from attending home games at their local football club, Charlton Athletic.

February 1999

The Macpherson report finds the police guilty of mistakes and “institutional racism” and makes 70 recommendations on changes to policing and wider public policy. It advises strengthening the Race Relations Act to tackle discrimination. The report also suggests a rethink of the principle of “double jeopardy”, to allow the retrial of acquitted defendants in exceptional circumstances if new evidence emerges of their guilt.

April 1999

The five men arrested in 1993 deny involvement in the murder in a TV interview with Martin Bashir. They accuse the programme’s makers, Granada Television, of editing the footage to make them look guilty.

The double jeopardy legal principle, preventing suspects being tried twice for the same crime, is scrapped for certain offences when there is new evidence.

January 2012

Dobson and Norris are found guilty of murder, 18 years after the event. The new evidence includes a blood spot on Dobson’s jacket – with a one in a billion chance of the blood coming from anyone other than Lawrence – and two hairs belonging to Lawrence found in an evidence bag recovered from Norris’s bedroom. The covert video evidence from the 1990s is revealed to show Norris talking about “skinning” black people and setting them alight. Both men receive life sentences. In a statement read out by his solicitors, Neville Lawrence says he is “full of joy and relief” at the conviction.

The Guardian and Channel 4 Dispatches reveal claims by Peter Francis, a former undercover police officer-turned-whistleblower, that he was sent to spy on the Lawrence family to find “dirt” on them in the period shortly after the murder in April 1993.
