Police in riot gear fired rubber bullets, tear gas and flash-bang rounds as they skirmished after dark with 300 to 400 demonstrators defying a dawn-to-dusk curfew outside a courthouse and adjacent park in downtown Kenosha.
But there was no immediate sign of buildings or cars being set ablaze, as happened on Monday night.
About three hours after declaring the protest an unlawful assembly, authorities had managed to push Tuesday night's crowd out of the downtown park, with demonstrators scattering down streets.
The disturbances came hours after Wisconsin Governor Tony Evers declared a state of emergency and vowed to deploy additional National Guard troops in a bid to restore order in the town, while the mother of the man who was shot, Jacob Blake Jr,
publicly appealed for calm.
