Banksy just posted photos of his latest piece... which IS the stuffed animal truck we were wondering about yesterday. The truck—which had the street artist's 1-800 number on it—was spotted around South Brooklyn yesterday afternoon—around 1 p.m. a tipster had told us, "It was so loud. Not sure but i think someone was in the truck banging as if the animals were trying to escape." Disturbing indeed—he calls the piece The Sirens Of The Lambs. Here's video from when it was first spotted yesterday:

As of 11 a.m. today the "slaughterhouse delivery truck [is] touring the meatpacking district," and then will tour citywide. We're headed over there now to see if we can spot it, and will update with specific current locations. In the meantime, here's the video Banksy posted on his YouTube today, showing some reactions to the truck:

And don't try tossing any tracking devices inside, as someone seems to have done with the mysterious street artist's other moving target (the waterfall and butterfly truck)—with his latest update he added this addendum: "If you're the person who stuck a tracking device on the garden truck you're now following a car service in Queens."

Update 3 p.m.: We visited the truck at Little West 12th Street by Washington Street and we asked the truck driver his name. He replied, "Joe." Last name? "The Farmer." Joe The Farmer couldn't really answer any of our other questions, "I don't really know much, I'm just a driver, a delivery guy. I'm just here delivering meat. Farm fresh meat."

He did admit that he didn't know where he was going next, "I just find out along the away."
