The death of George Floyd, an African-American man who died in police custody, has been declared a homicide following an official post-mortem.
He suffered a cardiac arrest while being restrained by Minneapolis police officers on 25 May, the report found.
The official post-mortem appeared to support the findings of a private examination carried out by medical examiners hired by the Floyd family.
That report, released earlier on Monday, said Floyd died from asphyxia.
