The personal trainer reflected on his intervention and said he dreaded to think what would have happened if he and his friends hadn’t intervened.
“It was in our best interests to make sure that this man didn’t get hurt, to get him out of there, and protect what’s happening at the moment, the movement,” Mr Hutchinson said.
More than 100 people were arrested amid the clashes after far-right counter-protesters gathered to “guard” historical monuments targeted recently by anti-racism protesters for their links to slavery and British colonialism.
Mr Hutchinson said BLM demonstrators and counter-protesters had clashed in an altercation near the top of some stairs.
In the unfolding chaos, the group of far-right protesters fled but left one man behind.
“I didn’t see what was actually going on at first…unfortunately for him, everyone set upon him,” Mr Hutchinson, who was not involved in the assault, said.
“There was a bit of a melee on the stairs, the guy ended up on the floor.”
Several of Mr Hutchinson’s friends rushed in to stop the fallen man being attacked further.
Mr Hutchinson entered the fray as his friends did their best to circle and shield the man.
“I was just thinking of, you know, a human being on the floor,” he recalled.
“I scooped him up like a fireman’s carry and sort of marched him out with the guys around me.”
As Mr Hutchinson carried him through the packed street, some protesters continued to try and strike the injured man.
“It wasn’t going to end well had we not intervened.”
He likened the frantic atmosphere and impromptu rescue to being in a “stampede”.
“His life was under threat.
“I could actually feel, you know, … strikes and hits as I was carrying him.
“If the other three police officers who were standing around when George Floyd was murdered had thought about intervening like what we did, George Floyd would be alive today,” Mr Hutchinson said.
In Britain, recent protests have triggered a national debate about the legacy of empire and its role in the slave trade.
Prime Minister Boris Johnson tweeted Friday that while Mr Churchill “sometimes expressed opinions that were and are unacceptable to us today,” he was a hero and “we cannot now try to edit or censor our past.”
Mr Churchill, whose first term spanned 1940-45, has long been revered for his leadership during World War II.
