Protests have erupted in Rochester in New York after police body camera footage revealed the disturbing arrest of a black man, who died a week later of suffocation.
Daniel Prude was detained by officers on March 23 while running naked through the street while experiencing mental health issues.
His brother had called police as he was concerned for his safety.
During the 11-minute confrontation between the police and the 41-year-old, a “spit hood” – which is used by police to prevent suspects spitting on them – was placed over his head while his hands were tied behind his back.
He was then placed face down on the road for two minutes and lost consciousness.
According to NPR, the Monroe County Medical Examiner’s Office ruled Mr Prude’s cause of death as “complications of asphyxia in the setting of physical restraint due to excited delirium due to acute phencyclidine intoxication.”
He died seven days later on March 30 after being taken off life support, although details of his arrest have only just emerged after Mr Prude’s family obtained the footage after a public records request.

The new details have sparked protests in the city, with NPR reporting police used pepper spray and tear gas on demonstrators near police headquarters on Wednesday, with nine people arrested.
There have also been protests held at the scene of Mr Prude’s arrest, with activists vowing to remain there until the officers responsible are punished.
“We want the larger community to know this is not something that happens in other cities, in other states, it happens right here in Rochester,” Black Lives Matter organiser Ashley Gantt told NPR.
Meanwhile, Mr Prude’s family are also calling for justice and have vowed to sue everyone involved in his death.
During a press conference on Wednesday, Mr Prude’s brother Joe described the death as “cold-blooded murder” and called for the officers involved to be sacked and charged.
“How many more brothers got to die for society to understand that this needs to stop,” Joe Prude said, according to the New York Times.
New York State attorney general Letitia James said an inquiry into the tragedy had been launched.
“The death of Daniel Prude was a tragedy, and I extend my deepest condolences to his family,” she said in a statement, according to Fox News.
“I share the community’s concerns about ensuring a fair and independent investigation into his death and support their right to protest.
“As with every investigation, we will follow the facts of this case and ensure a complete and thorough examination of all relevant parties. We will work tirelessly to provide the transparency and accountability that all our communities deserve.”
Mr Prude’s death is just the latest in a string of police brutality cases which have rocked the US and inspired the Black Lies Matter movement, which has since spread across the globe.
The movement has put the spotlight on systemic racism faced by the African-American community and other minorities and began after the death of George Floyd, who was killed by Minneapolis police officer Derek Chauvin in May.
