After descending on the Occupy Wall Street headquarters Wednesday night, Mayor Bloomberg told the protesters that they must vacate Zuccotti Park, temporarily, so it can be freshened up early Friday morning.

Deputy Mayor for Operations Cas Holloway issued a statement assuring demonstrators the “cleaning will be done in stages” and that they’ll “be able to return to to the areas that have been cleaned, provided they abide by the rules Brookfield has established for the park.” Basically, he’s telling them they can come back, but if they do what they’ve been doing for almost a month now, they can’t come back. So…?

Some say the operation is tantamount to an “eviction notice” and have vowed to bring their own cleaning supplies and spearhead their own sanitation program. However, that is very unlikely, and a handful of protesters have taken to Facebook to organize, vowing to lock arms and brooms if authorities try to forcefully remove them. The showdown is expected to take place around 7am tomorrow. (Photos: ANIMALNewYork) UPDATE: Police Commissioner Ray Kelly chimes in on the new policy the NYPD will be enforcing:

People will have to remove all their belongings and leave the park,” Kelly said today after a memorial ceremony in Battery Park. “After it’s cleaned, they’ll be able to come back. But they won’t be able to bring back the gear. The sleeping bags, that sort of thing, will not be able to be brought back into the park.
