On Monday, May 25, George Floyd, a 46-year-old black man, spent his last moments face down in a Minneapolis street, with the knee of a white policeman pressing firmly down on his neck.
The incident, which was live-streamed on Facebook by a bystander, saw Floyd protesting that he could not breathe, before he fell unconscious.
A short time later, he was pronounced dead in hospital.
Floyd was arrested as he matched the description of a suspect who was accused of trying to use a counterfeit $20 bill at a grocery store.
