A man screamed "all lives matter" before taking aim with a bow-and-arrow at people protesting the death of George Floyd.
Video posted to social media shows Brandon McCormick taking his hunting weapon out at a protest in Salt Lake City in Utah on Saturday.
Mr McCormick did not appear to actually shoot the weapon. Within a few moments he was tackled to the ground by the crowd.
He told local news outlet KSL-TV: "First, I got beat up when I yelled 'All Lives Matter'".
"Then I pulled out weapons and I got beat up some more.
"The cops grabbed me and my car got totalled... I lost everything, coming down here to try to protect [the police] with what weapons I had."
He added: "I back up the law enforcement."
Salt Lake City police said: "While we do not have the individual who was brandishing a bow and arrow in custody, we do know who he is. We intend to screen charges against him."
Protests have raged in cities across the US for five days, after Mr Floyd, a black man, died in police custody in Minneapolis earlier this week.
Derek Chauvin, the white officer who was seen kneeling on Mr Floyd's neck for at least eight minutes, has been charged with third-degree murder and manslaughter.
