Under the watchful eyes of San Francisco police officers, Occupy San Francisco protesters peacefully packed up their Justin Herman Plaza campsite early Tuesday.

Police had given protestors a 6 a.m. deadline to disassemble the tents, but said they could stay in the plaza because it was a city park and open to the public.

There was one minor confrontation that ended when a street vendor sprayed an Occupy protester with pepper spray.

The plaza along the Embarcadero -- dubbed Bradley Manning Plaza by the protesters for a former U.S. Army intelligence analyst accused of leaking classified information to WikiLeaks -- was turned into a bustling camp late last year before protesters were told to evacuate the plaza by city officials.

Protesters returned to the plaza Monday night following a day of rallies and marches to mark the one-year anniversary since the beginning of the Occupy Wall Street movement in New York.

Marches through downtown San Francisco streets disrupted traffic and Muni service sporadically before a 5 p.m. rally in front of 555 California St.

Following the rally, several hundred protesters marched to Wells Fargo headquarters at 420 Montgomery St., gathering there for several hours.

A brass band was among those marching, and another group stood behind a large yellow banner proclaiming themselves "Foreclosure Fighters," the banner's background scrawled with the names of banks and investment firms like Fannie Mae and Chase.

The protesters chanted as they marched, including Occupy mainstays like "Banks got bailed out, we got sold out" and appropriated chants for the day like, "The system has got to die, happy birthday Occupy."

Outside of Wells Fargo's headquarters, demonstrators threw debt slips and financial paperwork into a trashcan, symbolically sending the banks a message that they did not intend to repay their debts.

Others painted a large yellow mural on the street that said, "Democracy not debt."
