Police and crowds of people have clashed at a Confederate statue that's been fueling controversy in Virginia's capital.
Law enforcement tried to get people to disperse Friday night, as projectiles and smoke could be seen in video as people shouted.
The Richmond Times-Dispatch reported police released chemical irritants into the crowd.
Police said an unlawful assembly was declared at the monument around 10:17 p.m.
Authorities left shortly after 11 p.m., the newspaper reported.
State officials previously announced the grounds of the monument to Confederate Gen. Robert E. Lee would be indefinitely closed from sunset until sunrise every night.
