On Saturday, police had to push back crowds with bottles and cans being thrown in the air as protestors gathered at Grey's Monument in the centre of Newcastle.
The event began peacefully, as hundreds gathered in support of the Black Lives Matter movement - set up following the death of George Floyd, who died in police custody in America.
The trouble began around two hours after the start of the rally. A separate group formed directly opposite - many calling themselves Defenders of Newcastle.
