Police say an Occupy Wall Street protester dumped a tub of human waste down a public stairwell and inside a bank vestibule, and got caught on video.

Police said Occupy Wall Street protesters were captured on surveillance video dragging a large receptacle of human urine and feces to an open-air plaza at the corner of Nassau and Cedar streets last Wednesday evening, just before 8 p.m.

They then poured the waste down a set of stairs there, police said.

About 20 minutes later, one of the protesters entered a Chase ATM vestibule on Water Street and poured human waste inside there, police said.

A witness gave police the license plate number of the van used to transport the waste, and police were able to match the plate to its registered owner, a Philadelphia man.

He was arrested on Wall Street Saturday on charges of unlawful possession of noxious matter and aggravated unlicensed operation of motor vehicle.

Police also recovered a stun gun from inside his vehicle.
