“You see how quickly they make something aggressive?” the man filming says. “These guys are meant to be here to protect us”.
Mr Patton said there had been arrests and infringements issued to protesters in the same area on Monday, Tuesday and Wednesday night this week.
He said he was “absolutely concerned” with the behaviour and said the police presence in the area would be bolstered.
“There are some people there taking advantage of the situation who are anti-police, anti-government, anti-everything,” he said on 3AW.
“They mightn’t be happy with the lockdown we’re in, no one is [but] nothing entitles them to protest in public. They cannot do it.
“We’ll do what we can do and put more people there and arrest more people.”
The large group carried speakers playing the national anthem and protest songs.
Police were forced to block off roads and can be heard in footage posted online calling for the group to move.
