ATLANTA (AP) — With helicopters hovering overhead, police moved into a downtown Atlanta park and arrested around 50 Occupy Wall Street protesters who had been encamped there for about two weeks early Wednesday.

Like in many other cities, protesters had been camping in Woodruff Park to rally against what they see as corporate greed and a wide range of other economic issues.

Before police moved in, protesters were warned a couple times around midnight to vacate the park or risk arrest.

Inside the park, the warnings were drowned out by drumbeats and chants of “Our park!”

Organizers had instructed participants to be peaceful if arrests came, and most were. Many gathered in the center of the park, locking arms, and sang “We Shall Overcome,” until police led them out, one-by-one to waiting buses. Some were dragged out while others left on foot, handcuffed with plastic ties.

Police included SWAT teams in riot gear, dozens of officers on motorcycles and several on horseback. By about 1:30 a.m. Wednesday the park was mostly cleared of protesters.

State Sen. Vincent Fort was among those arrested and had come to the park in support of the protesters in recent days. He said the police presence was “overkill.”
