After weeks of being occupied by a combination of protesters and homeless people, City Hall Park was officially cleared out early Wednesday morning.

Police tell News 12 seven people were arrested during that initial removal process and that a brick was allegedly thrown at an officer who was not hurt.

Police say for the most part people left peacefully, but then some came back confrontational. Around 6:30 a.m., a small group of protesters was taken into custody.

“They were blocking the roadway, and one person was arrested for obstructing governmental administration because he prevented the arrest of another,” says Chief Raymond Spinella.

Around 3:40 a.m., hundreds of NYPD officers entered City Hall Park, which had been occupied by what News 12 is told was a combination of homeless people and Occupy City Hall protesters and forced them and their belongings out.

David Terry was one of the occupiers. He tells News 12 he is concerned for those who were in the encampment.

“Everybody was asleep and next thing you know they stormed into the place, and everybody started to run because nobody knew what was going on,” says Terry.

He says he worries about where everyone will go

“But what about the people; those are human beings, those people matter; they got to eat, they got to sleep, they got rights; what are we doing? Now they displace people? What are we doing? Where are the services to help these people?” says Terry.

The NYPD says a warning was given and that those in the park were there illegally.

“A warning was given when we first responded here. I don’t know, at least 10 minutes,” says Spinella.

The chief says a lot of cleanup is going to be happening, and it could take several weeks for them to completely clean up the park. He says until that’s complete, City Hall Park will be on lockdown.
