Death in Police custody

New charges for all four sacked officers over George Floyd’s death

The charge against Derek Chauvin has been elevated to second-degree murder, court documents show.

The other three officers, previously uncharged, face counts of aiding and abetting murder.

Floyd's death has sparked huge protests across the US against racism and the police killings of black Americans.

The vast majority of demonstrations over the past eight days have been peaceful, but some have turned violent and curfews have been imposed in a number of cities.

George Floyd death homicide, official post-mortem declares

He suffered a cardiac arrest while being restrained by Minneapolis police officers on 25 May, the report found.

It listed Mr Floyd's cause of death as "cardiopulmonary arrest complicating law enforcement subdual, restraint, and neck compression".

The examination also showed he had heart disease and recent drug use.

The findings of the official post-mortem were released shortly after those of a private examination carried out by medical examiners hired by the Floyd family.
