A video taken by an onlooker Monday evening shows a Minneapolis police officer keeping his knee on the neck of a motionless, moaning man at the foot of a squad car.
The man, who was later identified as George Floyd, later died.
Officers were able to get the suspect into handcuffs and noted he appeared to be suffering medical distress.
The man died soon after, the statement said, adding: "At no time were weapons of any type used by anyone involved in this incident.
The man who died was identified as George Floyd by Ben Crump, a prominent civil rights and personal injury attorney who said he had been hired by Floyd's family.
The video, captured by Darnella Frazier, begins with the man, who is black, groaning and repeatedly saying "I can't breathe" to the officer who has his knee on the man's neck.
