A white former police officer who shot dead a black motorist in Minnesota has been charged with second-degree manslaughter, prosecutors say.

Kim Potter was arrested and later released on $100,000 (£72,000) bail.

Mrs Potter says she shot Daunte Wright accidentally, having mistakenly drawn her gun instead of her Taser.

Responding to the charges, the Wright family's lawyer Ben Crump said the killing was an "intentional, deliberate, and unlawful use of force".

Both Mrs Potter and police chief Tim Gannon have resigned. The killing has sparked clashes between police and protesters in Brooklyn Center and late on Wednesday, several hundred demonstrators again defied a curfew to gather outside police headquarters.

Brooklyn Center is a suburb of Minneapolis, a city already on edge amid the trial of a white ex-police officer accused of murdering African-American George Floyd.

Minnesota's Bureau of Criminal Apprehension (BCA) said Mrs Potter was taken into custody on Wednesday morning at the BCA in St Paul. She was booked into Hennepin County Jail on probable cause second-degree manslaughter before bail was posted.

She is due to make her first court appearance on Thursday.

The charge carries a maximum sentence of 10 years in prison and a $20,000 (£14,500) fine. Prosecutors must show that Mrs Potter was "culpably negligent" and took an "unreasonable risk" in her actions, Reuters reported.

In a statement, Mr Crump said "no conviction can give the Wright family their loved one back".

"A 26-year veteran of the force knows the difference between a Taser and a firearm. Kim Potter executed Daunte for what amounts to no more than a minor traffic infraction and a misdemeanour warrant," he said.

Derrick Johnson, president of civil rights group the National Association for the Advancement of Colored People (NAACP), said "justice must prevail" after Mr Wright's death.

"A badge should never be a shield to accountability," he tweeted.

At a news conference on Wednesday, Brooklyn Center Mayor Mike Elliott called for people to protest peacefully.

"With the news of the decision to charge the former Brooklyn Center police officer with manslaughter comes a prolonged period of continued grieving, hurt and understandable anger," he said.

"Our task as a city and as a leadership is to allow for the expression of those very legitimate voices and to also create a pathway forward toward healing and renewal of our stability and strength as a community."

On Tuesday night, bottles and other projectiles were thrown at the Brooklyn Center police headquarters and officers responded by firing tear gas and stun grenades, according to reports.

Earlier on Tuesday the families of Mr Wright and Mr Floyd came together to demand an end to the killing of unarmed black Americans by police.

"The world is traumatised watching another African-American man being slain," Floyd's brother Philonise Floyd said.

On Monday, Police Chief Gannon said the shooting of Mr Wright - who had a one-year-old son - appeared to be an "accidental discharge" after Mrs Potter mistook her service pistol for a stun gun.

But the families have rejected the explanation.

Mr Wright's aunt Naisha said: "I watched that video like everybody else watched that video. That woman held that gun in front of her a long damn time."

Daunte Wright was pulled over for an expired tag on his car licence plate. Family members and advocates say he was racially profiled.

Bodycam footage showed Mr Wright fleeing from officers after they told him he was being arrested for an outstanding warrant.

As Mr Wright re-enters his car, Officer Potter is heard shouting "Taser" several times before firing a shot.

Mr Wright's mother Katie told reporters her son had called her after he was pulled over and that she had offered to give insurance details to police over the phone.

She said she heard police order him to get out of the vehicle. There was a scuffling sound and an officer told him to hang up the phone.

When she was eventually able to call back, his girlfriend answered and told her he had been shot.

"She pointed the phone toward the driver's seat and my son was laying there, unresponsive," she said in tears.

"That was the last time that I've seen my son."
