A mobile phone video made by the wife of a black man killed by police in Charlotte, North Carolina, shows her urging police not to shoot her husband.
The video of the shooting of Keith Lamont Scott provided to US broadcaster NBC News on Friday shows Rakeyia Scott approaching a vehicle as police interact with her husband, but does not show images of him actually being shot.
"Don't shoot him, he has no weapon," she can be heard saying as police yell at Scott to "drop the gun." After shots are heard being fired, she can be heard yelling, "he better not be [expletive] dead."
It is unclear from the footage whether Scott actually has a weapon, and authorities have said they will not yet release separate video from police cameras.
The shooting has led to several nights of sometimes violent protests in the city of Charlotte this week, even as protests remained largely peaceful overnight Thursday.
Protesters have called for the release of police video, but officials have said it is too soon to do so, leaving Scott's wife's mobile phone video to provide the first incomplete images of the incident.
Meanwhile police made an arrest Friday following the death of man who was shot during the protests.
Police Chief Kerr Putney said a suspect was taken into custody based on video evidence after a 26-year-old man was shot on Wednesday by another civilian during protests. The victim who had been on life support after initially surviving his wounds, died late Thursday.
Charlotte Mayor Jennifer Roberts on Thursday declared a curfew between midnight and 6 am, but protestors remained on the streets for about two hours after it came into effect.
Protesters briefly blocked a highway and police were concerned by reports that a violent group from another state was due to join the demonstrations, prompting the curfew.
One city building was vandalized and three arrests were made overnight, Putney said.
Hundreds of people marched through the city's business and government districts carrying signs and chanting slogans such as "hands up, don’t shoot,” and "we want the tape," calling for the release of police videos of the shooting and death of Scott.
The Tuesday shooting was followed by night-time demonstrations that turned violent, with 16 police injured and one person initially arrested.
More rioting broke out overnight Wednesday, with significant vandalism and looting in central Charlotte.
