The "Occupy SF" protesters, who have been camping out in the city's Financial District for the last couple of weeks, began marching earlier Wednesday from the Federal Reserve Bank at 101 Market St. toward Civic Center.
They arrived in Civic Center Plaza around 1 p.m., with more than 200 people shouting chants such as "Banks got bailed out, we got sold out."
At the front of the march was a group of people holding a large sign that said "Stop the War on Working People."
The march continued north on Polk Street toward the federal building on Golden Gate Avenue with a couple of dozen police officers on motorcycles accompanying the protesters as of 1:30 p.m.
The protest and march is being held in solidarity with Occupy Wall Street, which describes itself on its website as a "leaderless resistance movement" using nonviolent means to protest the nation's growing disparities between the rich and poor.
The site says, "We are the 99 percent that will no longer tolerate the greed and corruption of the 1 percent."
