Police and protesters clash in the City of London guardian.co.uk

Police have arrested 11 people after a day of demonstrations in London which saw anti-capitalists from the Occupy movement protest outside the Bank of England.

The arrests were made for public order offences linked to the day's demonstrations after campaigners marched on the banking institution late on Saturday afternoon.

The protest by 300 demonstrators in the City of London was part of a global day of action in which thousands staged rallies in cities including Moscow, New York, Athens and Madrid.

Campaigners gathered outside St Paul's Cathedral for a rally before embarking on a march which ended outside the Bank of England.

The demonstrators were closely shadowed by City of London police who set up a small kettle around protesters sitting on the steps outside the Royal Exchange building.

Demonstrators were given a deadline to leave the area but some resisted, resulting in several arrests.

Occupy claimed some police officers used "aggressive" force as they attempted to move protesters from the area outside the banking institution.

Protester Matt Varnham said: "Police have been diving in to where people were standing on mass. They were pushing people and being very aggressive. It's been very violent."

By 11pm on Saturday night, the majority of police officers had left the area, while some protesters remained.
