Four Minneapolis police officers have been fired a day after the death of a Black man who went into medical distress during an arrest for a nonviolent offense.

A video filmed by witness Darnella Frazier showed a handcuffed Floyd lying on the pavement with an officer’s knee on top of his neck.

Bystanders also urged the officer to stop pressing Floyd’s neck and call an ambulance.

The officer did not remove his knee from Floyd’s neck until an ambulance arrived with a stretcher.

“We all watched the horrific death of George Floyd on video as witnesses begged the police officer to take him into the police car and get off his neck,” Crump said in a statement.
