The protesters said they gathered in Foley Square, where a replica of the former camp at Zuccotti Park had been set up, and carried provided signs overnight Thursday as part of filming for an episode of "Law & Order: Special Victims Unit," MSNBC reported Friday.
MSNBC said it was unable to reach producers of the NBC program to confirm the filming.
"Please be advised that the T.V. show, Law & Order: Special Victims Unit will be preparing this area of the park for a scene to be filmed in the morning hours on Friday, December 9th. All items in park will be removed immediately upon completion of filming," a sign at the location read.
Protesters documented the event on Twitter using as tags "Mockupy" and "Fauxcotti."
"Ok, I've just snuck into a tent here at Fake Zuccotti Park and I'm going to live tweet all night and then the shoot tomorrow Ha …," Twitter user Newyorkist posted. "A lot of signs all over the place. Some wanted signs too, featuring CEOs."
