The police and city of Baton Rouge have been sued by Black Lives Matter activist DeRay Mckesson over mass arrests during protests against police killings.
DeRay Mckesson said police acted in a “militarized and aggressive manner” in detaining him and nearly 200 other people last month.
The protests were against the killing of Alton Sterling, a black man, in the Louisiana city.
Louisiana Governor John Bel Edwards has previously said the police’s response was appropriate.
DeRay McKesson was held on July 9 on a charge of obstructing a highway.
In the lawsuit, the Black Lives Matter activist and two other fellow protesters claimed that police were unnecessarily aggressive during the arrests.
The document said that “defendants used excessive force in attacking, battering, beating and assaulting plaintiffs and class members without provocation or the need for defense”.
The three arrested protesters said they wanted the lawsuit to have class action status.
Alton Sterling’s death was one of a string of police killings of black people by white police officers in recent years that triggered mass protests and rekindled debates about race relations in the United States.
Black Lives Matter protesters have been demonstrating in Minneapolis over the police shooting of Jamar Clark who witnesses say was unarmed and handcuffed at the time.
A state agency is investigating the incident, which happened on November 15. Relatives of the man concerned say he is on life support.
On November 16, Minneapolis Mayor Betsy Hodges called for a federal civil rights investigation into the case.
Black Lives Matter gained prominence after the police shooting of a black teenager in Ferguson, Missouri, in 2014.
That sparked protests nationwide about the police use of excessive force against African Americans.
Jamar Clark, a 24-year-old black man, was shot after police were called to a reported assault, and police say he “interfered” with the paramedics assisting the assault victim.
Police officers have said “misinformation” is spreading about Jamar Clark case, and some have told reporters he was not handcuffed.
On November 15, about 150 people gathered to demonstrate at the scene of the shooting and some camped out outside the police station.
The officer involved in the shooting has not been identified yet but two officers have been placed on paid leave.
Black Lives Matter organizers are demanding the release of any video footage that may exist of the altercation.
“We have been saying for a significant amount of time that Minneapolis is one bullet away from Ferguson,” Jason Sole, chair of the Minneapolis chapter of the National Association for the Advancement of Colored People (NAACP), told Minnesota Public Radio.
“That bullet was fired last night. We want justice immediately.”
Jamar Clark has convictions for making terroristic threats, aggravated robbery and possessing a small amount of marijuana.
In 2013, Minneapolis police shot and killed 22-year-old black man Terrance Franklin, who was suspected of burglary.
Minneapolis is participating in a federal Justice Department program for increasing trust between police and their communities.
A Hillary Clinton campaing rally at Clark Atlanta University has been interrupted by Black Lives Matter activists as she began a speech about reforming the criminal justice system.
The Democratic presidential contender spoke over the shouting, saying if elected she would carry on the work on President Barack Obama.
The group of 10 Black Lives Matter protesters were quickly escorted away.
They have interrupted campaign events to highlight police brutality, racism and mass incarceration.
The activists have mostly targeted Democrats – including Hillary Clinton and her chief rival Vermont Senator Bernie Sanders.
Hillary Clinton and Bernie Sanders have responded to the protests with policy proposals, meeting activists and talking about racial issues on the campaign trail.
The Black Lives Matter movement was originally formed after George Zimmerman, a Hispanic man in Florida, was acquitted of the shooting death of black teenager Trayvon Martin.
It grew to greater prominence after a white police officer killed Michael Brown – an unarmed black teenager – in Ferguson, Missouri, last year.
The protest movement has continued to gain strength over the past year after several controversial police-involved deaths of black people including those of Freddie Gray and Sandra Bland.
Friday’s rally was entitled “African Americans for Hillary”. Guests included pop singer Usher and civil rights activist and Congressman John Lewis.
The crowd of about 2,000 chanted “Let her talk!” and John Lewis asked them to stop.
“I’m sorry they didn’t listen, because some of what they demanded I am offering and intend to fight for as president,” Hillary Clinton said.
“We have to come together as a nation.”
In 1994, Hillary Clinton lobbied for one of the largest crime bills in US history, the Violent Crime Control and Law Enforcement Act, which provided billions for prisons. The law also introduced the “three strikes” policy, which called for mandatory life imprisonment without parole for federal offenders with three or more felony or drug trafficking convictions.
Hillary Clinton has changed her position since she has been on the campaign trail, calling for the end of mass incarceration and expressing her concern over police violence and black people.
On October 30, Hillary Clinton also proposed a legal ban on racial profiling by police.
The policy would forbid federal, state and local officers from “relying on a person’s race when conducting routine or spontaneous investigatory activities,” unless they have information linking a suspect to a crime.
Hillary Clinton also supported the “ban the box” movement, an effort to prevent job applicants from being disqualified because of their criminal history.
The City of North Charleston in South Carolina has reached a $6.5 million settlement with the family of Walter Scott, an unarmed black man shot dead by a white police officer in April 2015.
North Charleston City Council approved the deal in a unanimous vote.
Walter Scott, 50, was shot in April by Officer Michael Slager while running from a routine traffic stop.
It was one of several cases across the US in which unarmed black men died during encounters with police officers.
Officer Michael Slager was charged with murder and dismissed from the police force.
A police dashboard camera caught the moment Walter Scott ran from his car, while footage from a bystander’s mobile phone showed the officer firing eight shots at him as he fled.
“This is a very difficult period for the Scott family. I know they are glad to have this part behind them so their healing process can continue,” said North Charleston Mayor Keith Summey in a statement quoted by the Washington Post.
“As a result of this tragedy, important issues have been discussed, not only in North Charleston, but around the country. Citizens have become engaged in this process and government officials are listening.”
In July, New York City agreed to pay $5.9 million to the family of Eric Garner, who died after allegedly being put in a chokehold by a police officer.
In September, the City of Baltimore agreed to pay $6.4 million to the family of Freddie Gray, who died of a critical spine injury while in the back of a prisoner transport van in April.
Michael Slager has been detained in solitary confinement pending his trial. If convicted, the former officer faces from 30 years to life in prison without parole.
Tyrone Harris, who was shot by Ferguson police during events marking the first anniversary of the killing of unarmed black teenager Michael Brown, has been charged with assaulting officers, prosecutors say.
Tyrone Harris, 18, was critically wounded in a gun battle with police on August 9.
The authorities have declared a state of emergency in Ferguson, Missouri.
Michael Brown’s death triggered a wave of demonstrations over the use of excessive police force by officers.
The 18-year-old was shot in August 2014 by white police officer Darren Wilson, who was later cleared of any wrongdoing by a grand jury and the DoJ.
On August 10, some 50 people were shown on local news networks being arrested after blocking the main courthouse in St Louis, including civil rights activist Cornel West.
Rallies were due to take place in parts of St Louis and other major US cities as part of a day of civil disobedience called by activists.
Hundreds of people stood silent on August 9 for four-and-a-half minutes at the spot where Michael Brown was killed in Ferguson, representing the number of hours that his body lay in the street unattended.
However, the day of peaceful and somber commemorations turned violent late at night when, according to police, a gunfight erupted between two rival groups on West Florissant Avenue.
Police say Tyrone Harris was armed and opened fired, but his father has described their account of events as “a bunch of lies”.
Prosecutors filed 10 counts of charges against him, including assaulting an officer.
Police said Tyrone Harris was among six people who fired at an unmarked SUV with plainclothes detectives inside, who then fired back.
Tyrone Harris’ father told the AP news agency that his son, a close friend of Michael Brown, was shot between eight and 12 times as he was running away.
The gunmen “were criminals; they weren’t protesters,” he said, adding that the officers were not wearing body cameras – a major concern cited by protest groups.
Four police officers have been placed on administrative leave.
Photos from the scene showed a young black man lying bloodied on the ground. He was face down and handcuffed.
Announcing a state of emergency on August 10, the authorities in St Louis county placed police chief Jon Belmar in charge of Ferguson and the surrounding areas.
US attorney Loretta Lynch denounced the incident on Sunday, saying “not only does violence obscure any message of peaceful protest, it places the community, as well as the officers who seek to protect it, in harm’s way”.
It also drew criticism from protest groups, including the Ferguson Action Council and Organization for Black Struggle which described the police response as “excessive”.
John Gaskin III, a member of US rights group NAACP, told AP he did not expect unrest to escalate in Ferguson in the same way it has over the past year.
However, he warned, not many people would believe the police officers’ account of Sunday night’s events as “there’s still a tremendous level of distrust between law enforcement and the community”.
There have been a number of high-profile shootings of unarmed black men in US cities in recent months.
The most recent case involved 19-year-old Christian Taylor who was shot dead by a white police officer after he was spotted on surveillance footage vandalizing cars in Arlington, Texas, on August 7.
People in Ferguson, Missouri, are commemorating the first anniversary of the killing of unarmed black teenager Michael Brown.
On the eve of Sunday’s anniversary, several hundred marched through Ferguson in his honor, led by his father.
The shooting of Michael Brown by white police officer Darren Wilson sparked demonstrations across America.
Along with killings of unarmed black men elsewhere in the US, it also fuelled a national protest movement against racial bias by the police.
Activists and religious figures from across the country are among those who have gathered this weekend in Ferguson, a suburb of St Louis, Missouri.
Saturday’s rally was peaceful and heavily policed.
Michael Brown’s father, also called Michael, said: “Some families got justice through Michael Brown’s legacy, and that helped them. But I’m still trying to get through.”
On Sunday, a march is planned from the site of the shooting to a local church.
Participants are expected to observe a four and a half minute silence to reflect the approximately four-and-a-half hours that Michael Brown’s body lay in the street.
The protests, which sometimes involved violent clashes between demonstrators and police, continued in Ferguson for weeks after the killing.
The protest movement gained fresh impetus in November, when a grand jury decided not to charge Darren Wilson.
Officer Darren Wilson, who argued that he was acting in self-defense, resigned from the police force in November.
In March, a justice department investigation found evidence of widespread racial bias in the Ferguson police department.
The report led to several high profile resignations, including the chief of police.
The “Black Lives Matter” movement that emerged in the wake of 18-year-old Michael Brown’s death has focused attention on the troubled relationship between black communities and police forces in a number of US states.
