UPDATE: New York authorities are confirming that the cleanup and eviction have been postponed. See Josh’s feed below for a vivid account of the tense night, and a series of mini-profiles of protesters.

The owners of Zuccotti Park, where Occupy Wall Street has made its camp for nearly a month, released a set of rules Thursday that seems intended to evict the protesters permanently. The rules ban camping in the park or lying down on sleeping bags or under tarps. (See document below.) Brookfield Office Properties also announced plans to begin cleaning the park in three stages starting at 7 a.m. Friday—effectively a notice to protesters that they need to be gone by then or face the consequences. I’ve been reporting from Zuccotti Park since last weekend; for continuous updates during the eviction showdown see my tweets here (with the latest up top), or follow me on Twitter at @JoshHarkinson.
