The police death of George Floyd has sparked peaceful protests and scenes of violent unrest amid calls for justice in the US city of Minneapolis.
Mr Floyd, who worked as a club security guard, died after he was pinned down in the street as he was arrested by four police officers.
A white police officer, Derek Chauvin, 44, put his knee on the back of Mr Floyd's neck for about eight minutes as the 46-year-old unarmed black man lay face down gasping for air and pleading "I can't breathe" as a bystander shouted "you're killing him".
Mr Floyd was arrested after he allegedly tried to use a fake $20 bill at a corner shop on Monday night, and police claim he was "under the influence" in the driver's seat of a car.
