A man who wore a Guy Fawkes mask during a G20 protest has been charged with carrying a prohibited item in the security area.
The 44-year-old was arrested on the corner of Tank St and North Quay about 1.45pm on Saturday.
He has been issued with an exclusion notice and will appear in court on December 4.
It's the second such charge issued on the first day of the summit.
Earlier two women were taken to police headquarters for reportedly carrying gas masks. One, a 25-year-old, was later charged with carrying an unspecified prohibited item.

Meanwhile, a video of a protester - once jailed in the US for helping disable a war plane - being arrested for ignoring his G20 ban for a second time has appeared on social media.
It shows Ciaron O'Reilly surrounded by police, yelling "Free Julian Assange, Free Chelsea Manning" (formerly Bradley Manning, the US Army soldier convicted for leaking classified documents) before entering a police van.
Police could not immediately confirm his arrest.
O'Reilly was issued with a G20 exclusion notice on November 9.
But he ignored that and went to the G20 precinct at South Bank on Thursday. On that occasion he was arrested while waving posters that read "Free Julian Assange" and "Obama, O-Bomber, O-Bummer".
A Nine News reporter tweeted that O'Reilly knocked on her news car window and asked them to film his arrest on Saturday.
The seasoned activist once served 13 months in prison in the US for his involvement in disabling a B-52 bomber during the 1991 Gulf War.
