STATEN ISLAND, NY (PIX11) -- A poop-smearing man is now charged with arson after befouling his pregnant ex-girlfriend’s apartment door and setting it on fire, authorities said Tuesday.

The messy rampage began round 5:30 a.m. when Rasheen Harrison, 24, stripped naked inside the elevator of his former girlfriend's apartment building on the 300 block of Vanderbilt Ave, according to silive.com. 

He went straight to her apartment, and, while reportedly screaming obscenities and claiming to be the devil, pasted his own excrement on the door and then tried to ignite it -- using his own clothes to build the fire.

Police reportedly arrested a naked and filthy Harrison at the scene of the crime.  Safe inside the apartment during the entire episode were his six-months pregnant ex-girlfriend, two children and another person, possibly a man, according to reports.

The Daily News reported that Harrison’s poop attack didn’t end there, however.  After cops locked him inside a holding cell at the 120th Precinct on Staten Island, the poop Picasso began to smear a feces mural on the walls.

The Daily News reports that Harrison, who goes by the nickname of Illuminati, was mad at his ex for stealing his cell phone.

Harrison was reportedly taken to Bellevue Hospital for psychiatric observation.

Harrison now faces charges of arson, criminal mischief, reckless endangerment, menacing and endangering the welfare of a child, according to Staten Island DA Daniel Donovan.
