Police in Minneapolis will be banned from using chokeholds following the widespread protests sparked by George Floyd's death.
Negotiators for the city of Minneapolis agreed with the state of Minnesota to ban the restraint method and the City Council is expected to approve the agreement later on Friday.
They have also called for police to be required to report and intervene any time they see an unauthorised use of force by another officer.
The moves are part of a stipulation between the city and the Minnesota Department of Human Rights, which launched a civil rights investigation this week in response to the death of Mr Floyd in police custody on May 25.
The agreement, which will be enforceable in court, would require any officer – regardless of tenure or rank – to immediately report the use of any neck restraint or choke hold from the scene to their commander or their commander’s superiors.
Similarly, any officer who sees another officer commit any unauthorised use of force, including any choke hold or neck restraint, must try to intervene verbally and even physically.

If they do not, they would be subject to discipline as severe as if they themselves had used the prohibited force.
Mr Floyd, a 46-year-old black man, died on May 25 after a white police officer pressed his knee on his neck for nearly nine minutes.
From Paris and London to Tel Aviv, Sydney, Johannesburg and Rio de Janeiro, Mr Floyd's death has sparked demonstrations across the world, with protesters decrying inequality, police brutality and other problems in their own countries.
The family of Mr Floyd and others including celebrities, civil rights activists and politicians gathered in Minneapolis on Thursday for a memorial marking his death.
At the first service to be held over six days across three communities where Mr Floyd was born, grew up and died, Mr Floyd's brother Philonise recounted their childhoods and said: "I loved my brother, we had so many memories together... everybody loved George... he touched so many people's hearts."
Giving a eulogy, Rev Al Sharpton said: "George Floyd's story has been the story of black folks. Because ever since 401 years ago, the reason we could never be who we wanted and dreamed to be is you kept your knee on our neck.
"It's time for us to stand up in George's name and say, 'Get your knee off our necks!"'
The protests on Thursday night in US, while boisterous at times, were largely orderly.
Demonstrations on previous evenings had been mostly peaceful, but also punctuated by sporadic arson, looting and clashes between protesters and police.
The apparent change in mood reflected a determination voiced by many protesters and organisers in recent days to transform outrage over Mr Floyd’s death into a renewed civil rights movement and seek reforms to the US criminal justice system.
Former Minneapolis officer Derek Chauvin has had his murder charge upscaled from third-degree to the more severe second-degree over the incident, while three other former officers have also now been charged with aiding and abetting murder.
