SAN FRANCISCO -- Protesters in San Francisco took down tents overnight to meet a 6 a.m. Tuesday deadline set by police, according to media sources.

Police are keeping an eye on a small group in Justin Herman Plaza, according to KGO-TV.

The protesters had marched Monday evening in the Financial District to mark the anniversary of the Occupy Wall Street movement.

As many as 500 marchers blocked streets and rallied for an end to financial inequality.

The rally commemorated those held one year ago, on Sept. 17 in New York City's financial district, when demonstrators protested big banks and started worldwide protests.

Earlier Monday, Occupy Wall Street protesters marched around Manhattan's financial district. As many as 100 were arrested.

In the East Bay, protesters rallied at the Wells Fargo Bank at the downtown Berkeley BART station.

In Davis, about 50 protesters demonstrated Monday morning in front of a Monsanto plant, saying they want to shut down the local office of the multinational biotechnology company.
