A vulnerable black man died after he was hooded by police who held his head face down to the ground for two minutes.
Daniel Prude, 41, was suffering from mental health issues when police restrained him in a New York road in March – two months before George Floyd’s killing and a series of similar incidents sparked widespread protests in the US.
The incident was captured in disturbing police body camera footage.
He died a week later in hospital but the news has only now emerged after his family held a news conference on Wednesday.
Daniel’s brother Joe said: “I placed a phone call for my brother to get help, not for my brother to get lynched.
“What is their sentence? You killed a defenceless black man.
“A father’s son, a brother’s brother, a nephew’s uncle.”
Daniel had been running through the streets naked before police arrived at the scene and restrained him.
In the footage, police can be heard ordering him to “get on the ground,” “put your hands behind your back” and “don’t move”.
Daniel was unarmed and can be heard saying “sure thing” in the video.
He swears and shouts at the police but does not show any physical resistance, the footage shows.
Daniel reportedly told police he had coronavirus before they put a ‘spit hood’ over his face to protect themselves.
One officer appeared to be pressing down on his head with both hands and told him to “calm down” and “stop spitting”.
Officers can then be heard saying “he’s puking” before he stops writhing and goes quiet.
The footage then shows him lying on the ground as he’s given chest compressions.
Daniel was taken in an ambulance to hospital but he was taken off life support on March 30.
A post mortem seen by the Rochester-based Democrat and Chronicle newspaper, Daniel’s death was a homicide caused by “complications of asphyxia in the setting of physical restraint”.
PCP, a strong hallucinogenic drug, was also reported to be a complication.
The officers involved are not believed to have been suspended yet.
The footage was released as news emerged of a black teenager shot dead by police officers as he allegedly tried to run away from the scene of an investigation, sparking more furious protests.
Black Lives Matter protesters descended on a police station in Washington DC on Wednesday evening after 18-year-old Deon Kay was killed.
Police chief Peter Newsham said 7th District officers were acting on information weapons were in a vehicle in the area, but as they approached two passengers fled.
He said two firearms were recovered and two people were arrested, adding officers believe Kay “had a gun at the time”.
It was the latest in ongoing demonstrations in response to police violence against black people in the US which began in May after George Floyd was killed in Minneapolis.
