Thousands of Occupy Wall Street activists have clashed with police after swarming banks and businesses in New York as part of the movement's massive May Day protests across the country.
In a deliberate attempt to bring large-scale European-style May 1 protests to America for the first time, Occupy called for a general strike, urging workers to attend marches rather than work.
The biggest swell of defiance was in New York, where protesters had planned to bring the city to a halt by blockading major arteries like the Brooklyn Bridge - and where at least 30 were arrested.

In Los Angeles, at least a half a dozen rallies were planned. A rally was also planned in Minneapolis.
In Atlanta, about 100 people rallied outside the state Capitol, where a law targeting illegal immigration was passed last year. They called for an end to local-federal partnerships to enforce immigration law.
Back in New York, officers brought out kettling nets to cordon off any unruly protesters, while there were reports on Twitter of teargas being used along Broadway near Union Square.
'Remember remember, the 1st of May, the day we made the bankers pay,' read one sign held by a protester marching through Times Square.
