RIOTING broke out in the US city of St Louis on Wednesday night after police shot a young black man dead.

Police in riot gear used tear gas and rubber bullets after nearly 100 angry residents took to the street in the area around Page Boulevard and Walton Avenue in the afternoon. Three people were arrested.Later that evening some set up a “flaming barricade” and torched a vacant building and a car.

The shooting of 18-year-old high-school graduate Mansur Ball-Bey recalled that of unarmed black teenager Michael Brown a year ago in Ferguson, a suburb of the eastern Missouri city.
