Dozens of Occupy Wall Street protesters have been arrested as they attempted to march onto the New York stock exchange to mark two months since the movement against corporate greed began.

New York City police arrested the protesters after they refused to end a blockade of a street intersection in the city's financial district. Some protesters, who resisted orders to leave, scuffled with the officers.

Protesters planned to march from Zuccotti Park in lower Manhattan to Wall Street as part of a co-ordinated effort to shut down the exchange. They hoped to interrupt business by preventing financial workers from reaching their offices.
