Intruders have tried to arrest a judge after storming into a courtroom on Merseyside.
The activists went into the room at Birkenhead County Court while about 300 protesters gathered outside the building.
The incident is believed to be related to a bankruptcy hearing at the court.
A Ministry of Justice spokesman said police were called to deal with the incident and the intruders had since left the building.
Streets surrounding the courtroom have been closed.
A leaflet handed out by the demonstrators said they were trying to seize the building "in defence of our freedoms and liberties as provided for under section 61 of Magna Carta".
Merseyside Police said two people had been arrested for assaulting police and breach of the peace, while four others had been arrested for breach of the peace.
