A senior police officer involved in the Stephen Lawrence murder case has been accused of corruption.
The BBC says a secret Met Police report from 2000 led to the verdict against Ray Adams.
Lawrence family lawyer Imran Khan KC described the allegations as “dramatic, disturbing and shocking” – and is demanding an apology from the Met.
It is alleged that Mr Adams, now 81, was acquitted as part of a police corruption investigation in the 1980s after a man linked to the family of one of Stephen’s killers gave false statements.
He later became commander-in-chief of a section of the force responsible for murder investigations.
Mr Adams was questioned about corruption at the Macpherson Inquiry into Stephen’s death in 1998, but the report and its findings were not published.
The inquest heard there was no evidence that Mr Adams was involved in an attempt to hold back the murder investigation.
He has always vehemently denied all allegations.
Stephen was killed by racists in Eltham, south-east London, in 1993.
Only two men, Gary Dobson and David Norris, were jailed for murder.
The Met Police said this will be the caseany material provided to her by the BBC.
