New York police has arrested more than 70 people yesterday in Times Square during a march of 20,000 of Occupy Wall Street protesters from the city’s Financial District to midtown Manhattan.

The demonstrators swamped Times Square, stopping traffic, in what was thought to be the largest Occupy demonstration in the U.S. so far.

The arrests come one day after the Zuccotti Park’s owner backed down from an attempt to move the demonstration.

Many of the Occupy demonstrators in the iconic square of New York City came from around US and did not come up from the encampment.

The Rome demonstration came a day after Premier Silvio Berlusconi barely survived a confidence vote as Italy, with a national debt ratio second only to Greece in the 17-nation eurozone, is rapidly becoming a focus of concern in Europe’s debt crisis. Italian government has passed a 60 billion-euro austerity package that has raised taxes and will make public health care more expensive.

Demonstrators worldwide shouted their rage against bankers and politicians they accuse of ruining economies and condemning millions to hardship through greed and bad government but most other protests were carried off peacefully.
