Video Shows White US Cop with Knee on Neck of Motionless Black Man Who Later Died

The video, captured by Darnella Frazier, begins with the man, who is black, groaning and saying repeatedly, "I can't breathe" to the officer with his knee on the man's neck. The officer is white.

"Please," he pleads. "I can't breathe," and continues to moan.

An officer keeps insisting he get in car he keeps saying he can't, CBSNews reported.

"My stomach hurts. My neck hurts. Everything hurts. … (I need) water or something. Please. Please. I can't breathe, officer. … I cannot breathe. I cannot breathe." That was followed by more groaning.

A female bystander points out the subject's nose is bleeding.

In an ongoing commentary permeated by cursing, a male onlooker says, "That's bulls—t, Bro. You're stopping his breathing right there, Bro. Get him off the ground, Bro. You're being a bum right now."

The man says the officer is "enjoying that. He's a bum, Bro. You could have put him in the car by now. He's not resisting arrest or nothing. You're enjoying it. Look at you. Your body language – you bum. You know that's bogus right now."

The female onlooker repeatedly urges the officers to check the subject's pulse. "He's not responsive right now," a bystander says. "He's not moving."

Then, an ambulance arrives and takes the man away.

"You just really killed that man, Bro," the male onlooker says.

Frazier, who took the video, says directly beneath it on her Facebook page, " They killed him right in front of cup foods over south on 38th and Chicago!! No type of sympathy. #POLICEBRUTALITY."

The man died soon after, the police said in a statement, adding, "At no time were weapons of any type used by anyone involved in this incident. … Body worn cameras were on and activated during this incident."

Later, Minneapolis police said the FBI is joining the investigation of the incident.

Two of the officers involved have been put on paid administrative leave, the department says.
