The Police Department has released stomach-churning footage of alleged Occupy Wall Street demonstrators dumping a disgusting mix of what is said to be human waste in a bank and a stairwell last week.

According to the police department, surveillance cameras captured protesters on March 14 dragging a tub filled with a mix of urine and feces into a public plaza at Nassau and Cedar Streets at 8 p.m. They then poured the concoction down a stairwell. About 20 minutes later, another camera caught a man dumping waste inside of a Chase Bank on Water Street. A witness gave investigators the license plate number of the van allegedly used to haul the smelly brew, and two days later they arrested 25-year-old Jordan Brooks Amos of Philadelphia. Mr. Amos is charged with unlawful possession of noxious matter, aggravated unlicensed operation of a motor vehicle, and criminal possession of a weapon due to a stun gun that was allegedly in his vehicle.

The gross video was immediately met with shock — and some skepticism — on Twitter.
