More than 700 people from the Occupy Wall Street protest movement have been arrested on New York's City's Brooklyn Bridge, police say.

纽约警方称，超过700多名参加“占领华尔街”运动的示威者在布鲁克林大桥被逮捕。

They were part of a larger group crossing the bridge from Manhattan, where they have been camped out near Wall Street for two weeks.

Some entered the bridge's roadway and were met by a large police presence and detained, most for disorderly conduct.

The loosely-organised group is protesting against corporate¹ greed.

They say they are defending 99% of the US population against the wealthiest 1%.

Occupy Wall Street called for 20,000 people to "flood into lower Manhattan" on 17 September and remain there for "a few months".

Several hundred remain camped at Zuccotti Park, a privately² owned area of land not far from Wall Street.

A police spokesman quoted by Reuters said the arrests came "after multiple warnings by police were given to protesters to stay on the pedestrian（行人的） walkway".

"Some complied and took the walkway without being arrested. Others locked arms and proceeded on the Brooklyn-bound vehicular roadway. The latter were arrested," the spokesman said.

Many were released again shortly afterwards, police said.

Some of the protesters said police had allowed them on to the roadway and were escorting them across when they were surrounded and the arrests began.

"This was not a protest against the NYPD. This was a protest of the 99% against the disproportionate power of the 1%," protester Robert Cammiso told the BBC.

"We are not anarchists³（无政府主义着） . We are not hooligans（小流氓） . I am a 48-year-old man. The top 1% control 50% of the wealth in the USA."

Another protester, Henry-James Ferry, said: "It is not fair that our government supports large corporations rather than the people.

"I only heard about the protest on day one when I came across it. I then decided⁴ to go back every day," he told the BBC.
