Terrence Floyd says while he wants protesters to stay in the streets until justice is served, his brother would not have wanted the community he loved to be destroyed.
George Floyd's brother has pleaded with people across the US to keep their protests peaceful as demonstrations against his death at the hands of Minneapolis police enter their seventh consecutive night.
Visiting the site of his brother's arrest and subsequent death for the first time, Terrence Floyd urged the minority of protesters who had turned violent to stop.
"If I'm not over here wilding out, if I'm not over here blowing stuff up, if I'm not over here messing up my community, then what are you all doing?" he told the protesters.
"You all are doing nothing, because that's not going to bring my brother back."
Before addressing the crowd, Mr Floyd knelt in prayer on the spot where his brother lost his life, now covered in floral tributes and protest signs calling for an end to police brutality against African Americans.
Mr Floyd was overcome with emotion, with two supporters holding him up at one point as he neared the site of his brother's death.
Hundreds of protesters surrounded Mr Floyd while he prayed, taking a knee to join him before he led them in chants of his brother's name.
Mr Floyd urged Minneapolis to continue demonstrating to ensure his brother's name would not be forgotten, but said George would never have wanted violence in his name.
"My family is a peaceful family, my family is god-fearing. Let's do this another way. Let's stop thinking that our voice doesn't matter and vote," he said.
"Do this peacefully. Please. My brother moved here from Houston and I used to talk to him on the phone. He loved it here. I know he would not want you all to be doing this."
Seven consecutive nights of protests have followed George Floyd's death, with Hennepin County medical examiners on Monday ruling his death was a homicide caused by "neck compressions" during his arrest.
Wearing a face mask featuring his brother's picture and the words 'we can't breathe', Mr Floyd led the crowd in chants of 'peace on the left, justice on the right', urging them to balance both as they demonstrate.
He ended his speech by saying "one down, three to go", demanding the three officers who stood by as Derek Chauvin pressed his knee on his brother's neck for nine minutes to also be arrested and charged.
