Last night, New York City police raided Zuccotti Park, the public square in Manhattan's financial district that became the home base of the Occupy Wall Street movement.

Over 150 people were arrested as the police cleared out all protesters. City workers eliminated the tents and other properties of the people who had camped out there for nearly two months. Sanitation crews then sprayed down the square in the early morning hours. The city does not want anyone to return and attempt to camp out in the park.

New York Mayor Michael Bloomberg presented the decision as his own, claiming “health and safety conditions became intolerable” in the park.

Legal teams on both sides are arguing in court today over whether protesters can return to the park and stay the night there.

Here is the chain of events through the night, according to the protesters:
