Daunte Wright shooting: Dozens arrested in fresh unrest in Minnesota
The clashes come as police say Daunte Wright, 20, died after an officer mistook her gun for a Taser.
About 40 people were arrested just north of Minneapolis in a second night of unrest over the police shooting of a black man.
Protesters in the city of Brooklyn Center defied a curfew and threw objects at police, who responded with flash grenades and tear gas.
Police said Daunte Wright, 20, was shot and died after an officer mistook her gun for a Taser during a traffic stop.
The shooting came as the high-profile George Floyd murder trial continues.
In a courtroom just a few miles away, ex-police officer Derek Chauvin is charged with murdering the African American man in May last year.
Derek Chauvin's defence team on Monday asked for jury members to be sequestered - separated from other people - as they might be swayed by the latest events. The judge denied the request.
