Four Minnesota police officers have been fired after the death of a black man who was taken into custody and seen on video being pinned down by his neck.
Minneapolis Police Chief Medaria Arradondo said the four officers were now “former employees”.
Footage shows the man, George Floyd, groaning and repeatedly saying “I can’t breathe” to the white officer.
The incident echoed that of Eric Garner, a black man who died being arrested in New York City in 2014.
The FBI has said it will investigate the Minneapolis incident, which took place on Monday evening.
Minnesota police said Mr Floyd died after a “medical incident” in a “police interaction”.
They said he had been suspected of committing forgery. On Tuesday afternoon, Mayor Jacob Frey confirmed the four officers involved in the incident had been “terminated”. “This is the right call,” he tweeted.
At a press conference earlier, Mr Frey had described the incident as “completely and utterly messed up”.
“I believe what I saw and what I saw is wrong on every level,” he said. “Being black in America should not be a death sentence.” It is the latest accusation of US police brutality against African Americans.
Recent high-profile cases include an officer in Maryland who fatally shot a man inside a patrol car.
The incident in Minneapolis began after officers located the man in his car, police said in a statement.
They were told the man, who has not been identified, was “sitting on top of a blue car and appeared to be under the influence”.
After being ordered to step away from the vehicle, the man physically resisted officers, according to police.
“Officers were able to get the suspect into handcuffs and noted he appeared to be suffering medical distress,” the statement added.
In the 10-minute video filmed by a witness, the man is kept on the ground by the officer and, at one point, says: “Don’t kill me.”
Witnesses urged the officer to take his knee off the man’s neck, noting that he was not moving. One says, “His nose is bleeding”, while another pleads, “Get off his neck.” The man then appears motionless before he is put on a stretcher and into an ambulance.
Police said no weapons were used during the incident and that body camera footage had been handed to the Minnesota Bureau of Criminal Apprehension, which is investigating the case.
After the video emerged, police said in a statement: “As additional information has been made available, it has been determined that the Federal Bureau of Investigation will be a part of this investigation.”
Speaking to US media on Tuesday, Chief Arradondo said the force’s policies “regarding placing someone under control” will be reviewed as part of the probe.
The FBI declined to comment. Minnesota Senator Amy Klobuchar – who has reportedly been shortlisted as Democratic presidential candidate Joe Biden’s running mate – issued a statement calling for a “complete and thorough outside investigation”.
“Justice must be served for this man and his family, justice must be served for our community, justice must be served for our country,” she said.
“I can’t breathe” became a national rallying cry against police brutality in the US after the July 2014 death of Eric Garner. Garner, an unarmed black man, uttered the phrase 11 times after being detained by police on suspicion of illegally selling loose cigarettes.
They were the final words of the 43-year-old, who died after a police officer placed him in a chokehold.
A city medical examiner ruled the chokehold contributed to Garner’s death. The New York City police officer involved in Garner’s deadly arrest was fired from the police force more than five years later, in August 2019′.
