VIDEO: At Least Nine Protesters Arrested After St. Louis Police Shooting

At least nine people were arrested Wednesday and St. Louis police used tear gas to clear a street of protesters after an armed man fleeing from officers was shot and killed when he pointed a gun at them, reports Fox News .

St. Louis Police Chief Sam Dotson said at a press conference late Wednesday night that a group of protesters who had blocked an intersection threw glass bottles and bricks at officers and refused orders to clear the roadway. Inert gas was used and when that didn't have any effect on the crowd, police turned to tear gas to clear the intersection, Dotson said. Those arrested face charges of impeding the flow of traffic and resisting arrest, he said.

In addition to the arrests, officers responded to reports of burglaries in the area and the fire department was called after a car was set ablaze, according to Dotson.

The chief blamed the crimes on people seeking "notoriety" in a neighborhood "plagued by violence." Dotson added that police would release video showing that officers gave multiple orders to clear the street and repeatedly warned that the tear gas would be used.

Dotson said two police officers serving a search warrant Wednesday afternoon at a home in a crime-troubled section of the city's north side encountered two suspects, one of which was 18-year-old Mansur Ball-Bey. The suspects were fleeing the home as Ball-Bey turned and pointed a handgun at the officers, who shot him, the chief said. Ball-Bey died at the scene.

Both officers were unharmed, according to a police report.
