Key events since George Floyd’s arrest and death

George Floyd’s death after his arrest by police officers in Minneapolis on May 25 2020 sparked widespread anger after millions of people saw video of the incident.

The four officers at the scene were quickly fired and soon charged over his death.

The agonising bystander video shows Mr Floyd repeatedly crying “I can’t breathe” and eventually going still as officer Derek Chauvin presses his knee on Mr Floyd’s neck.

The video’s release sparked immediate protests and sometimes violent riots nationwide and around the world.

Chauvin will go on trial on Monday in Minneapolis, facing charges of second-degree murder and manslaughter.
