LOS ANGELES — Eleven protestors were arrested Thursday in the biggest anti Wall Street-style demonstration yet in Los Angeles, with some 500 people rallying in the city's downtown district, police said.

Six men and five women were detained for trespassing by sitting down in the lobby of the Bank of America, said an LA Police Department (LAPD) spokesman.

Crowds -- including some from the "Occupy L.A." group which began protests at City Hall last weekend -- looked on as those arrested were escorted out the front door. They were bailed for $5,000 each.

The protest was led by the ReFund California campaign, which lobbies for banks to keep families in homes, pay their fair share of taxes and help rebuild poor neighborhoods.

"Money for Jobs and Housing, Not Banks and War" and "We Need Good Jobs," read some of the placards carried by protestors, who dispersed later in the afternoon.

Demonstrators have camped on the lawn of LA's City Hall since last Saturday as part of a nationwide series of demonstrations centered on anti-Wall Street protests in New York.
