Supporters of Michael Brown, the unarmed black teenager shot dead by a police officer on Saturday, have protested outside the police headquarters near where he died in St Louis.
Police last night arrested 32 people after rioting and looting by protesters broke out in Ferguson, a predominantly black area, before spreading to other parts of the city.
The teenager died after a struggle in a patrol car spilled out into the street, where the fatal shot was fired. It remained unclear why Brown was in the car.
Civil rights leader the Rev. Al Sharpton said that he had spoken with Brown's relatives and would visit St Louis to help the family.
