A New York police officer has been accused of giving a 'white power' symbol during the demonstrations in the United States.
Hundreds of Americans have taken to the streets in protest of the death of George Floyd, who died after white former-police officer Derek Chauvin knelt on his neck for several minutes.
In a brief four-second clip, a police officer on duty in Union Square can be seen using an 'OK' hand gesture which is commonly associated with white supremacy. By putting together the thumb and forefinger the symbol spells WP- White Power.
The video has prompted an investigation by the New York Attorney General.
The same hand signal was used during a 2019 court appearance by Brenton Tarrant, the accused shooter of the Christchurch Mosque Attacks.
The officer in the clip can be seen pulling the symbol before laughing with a colleague.
The video has now been viewed more than 8.6 million times, but officials are yet to comment on it.
Commenters have been calling for the officer's badge name and number to report him.
Boxing promoter Lou DiBella tweeted: "This video is clear enough to identify this @NYPD Officer. What kind of cop throws a white power sign at a civil rights protester? A white supremacist perhaps? How about taking action now before this smirking racist is responsible for another".
Comedian Kyle Ayers wrote: "Ah yes, another hero who signed up to protect and serve and not just a coward who wanted a license to abuse minorities, just a cop casually throwing up the white power sign and then laughing. Love tax-funding the salary of racists with no oversight".
Others have called for the officer to be fired and denied his pension.
New York Attorney General Letitia James urged viewers to send their complaints to her.
"Please report this and send the video to my office," she responded to the video.
"I want New Yorkers to know that I take my role to investigate the events of this weekend very seriously.
"I promise you a swift investigation with all of the facts. Please share any information, including visuals, with my office," she later said.
Protests around the US have seen local stores destroyed and looted.
One person was killed in Kentucky overnight when police returned fire while trying to disperse a crowd.
In a statement, Kentucky Governor Andy Beshear asked the state police "to independently investigate the event".
NBC says it's not clear who fired the fatal shot and no information about the victim has been released.
