UPPER EAST SIDE — On the street, 42-year-old Ekwan Hill, who prosecutors claim randomly shoved poop down a woman's pants and smeared feces on another woman's face and body, appears bold and imposing.

But during an exclusive jailhouse interview Friday he appeared shy and even fearful, declining to explain what happened.

"It's personal," the 6-foot-tall homeless man said, shaking his head.

Hill — bearded and wearing a dark green jumpsuit — declined to speak further, and his attorney has not responded to calls for comment.

He was charged with sexual abuse, menacing, public urination and harassment at his arraignment on Saturday and ordered to complete a psychiatric exam, according to a criminal complaint.

He's due back in court on Aug. 19, where his results will be discussed, according to the Manhattan District Attorney's office.

For now, he remains at MDC in Lower Manhattan since he did not post bail, which was set at $15,000 cash or $90,000 bond.

Hill was arrested on July 1 at a Brooklyn shelter after a Department of Homeless Services officer recognized him from surveillance photos released by police, authorities said. During the arrest, police found Hill's locker at the shelter filled with latex gloves and a T-shirt that Hill was seen wearing in one of the surveillance videos.

His first attack took place at 2:30 p.m. on June 27, when he walked up to a 33-year-old woman on East 91st Street and rubbed feces into her face and mouth with his open hand, police said. Then he threw more excrement at her and another person and fled, according to NYPD officials and the complaint.

Just hours later, at roughly 6:13 p.m., Hill grabbed a 27-year-old woman by the waist on East 74th Street and pushed feces down her pants and smeared it on her butt, the complaint states.

Video surveillance shows Hill throwing a pair of latex gloves onto the sidewalk as he fled the the second scene.

Hill has 21 prior arrests, including charges of assault and criminal possession of marijuana, police said.
