On his blog: “A City of London police inspector orders the media to leave the area as police ‘kettle’ protesters outside the Bank of England [Thursday 2 April 2009 in London].
“The police officer ordered members of the media to leave the area for 30 minutes under the threat of arrest by citing Section 14 of the Public Order Act 1986. The protesters had congregated to mark the death of a man who had died on an anti-G20 protest the day before.”
