George Floyd, 46, died on Monday and video showed him gasping for breath as a white policeman knelt on his neck.
Police fired tear gas at protesters as businesses were looted on Wednesday. More protests are planned for Thursday.
There have also been protests in Chicago, Illinois, Los Angeles, California, and Memphis, Tennessee.
The killing added to longstanding anger over the police killings of black Americans, including the recent cases of Ahmaud Arbery in Georgia and Breonna Taylor in Kentucky.
