According to a statistics of the US "CNN" network, the number of detainees reached 4 thousand people since May 26 until Monday morning due to the wave of protests that swept a number of American cities.
The protests, which in some areas turned into looting, ransacking and burning of government and commercial facilities, are still continuing despite the imposition of a curfew in some areas and the deployment of more police and patriotic guards.
Police fired tear gas to disperse demonstrators in front of the White House on Sunday evening.
Government sources said a curfew was imposed in the major cities to stop riots and protests over the Minneapolis incident.
Reporters said that the tear gas was used to disperse the crowds of people who gathered outside the walls of the White House, chanting, lighting and carrying protest placards.
On Sunday, a driver of tanker truck tried to make way between thousands of demonstrators on a bridge in central Minneapolis, Minnesota, which required the intervention of a large number of police officers.
The local police said in a statement that there were likely no injuries reported among the demonstrators, describing what happened as a very disturbing incident.
The truck driver was injured, but his life is not in danger, and he was arrested and taken to hospital.
Confrontations broke out between security forces and protesters in more than twenty American cities, including Los Angeles, Chicago and Atlanta.
Fierce clashes prompted the authorities in these cities to impose a night curfew, while several states called in the National Guard to help control the civil unrest that the United States had not seen in several years.
From Seattle to New York, tens of thousands demonstrated to demand the charge of premeditated murder and the arrest of others in the case of George Floyd, who died of suffocation after the white policeman, Derek Chauvin, brutally crouched his neck.
In Los Angeles, security agents fired rubber bullets and used batons to disperse demonstrators who burned a police car.
