A 13-year-old boy has been charged with the shocking rape of an 8-year-old girl in a New York Public Library branch in Harlem, after the victim told her mother that she was lured into a bathroom and attacked

The suspect, whose name is being withheld because he is a minor, was charged with second-degree rape and unlawful imprisonment after being questioned at the 32nd Precinct station house. The boy was caught on security cameras at Countee Cullen Library on W. 136th Street near Lenox Avenue leading the girl into a bathroom. The gruesome attack occurred shortly after the young victim arrived at the library with her 8-year-old brother and her 54-year-old female babysitter. The girl apparently wandered away from her brother and babysitter as they were perusing books. She went up to the second-floor mezzanine where she encountered the suspect, whom she recognized from previous trips to the library. “He verbally lures her into the bathroom,” a law enforcement source said. “Once they’re inside the bathroom, he locked the door so she couldn’t get out.” During the sickening 20-minute assault, the pubescent perpetrator, described by sources as a troubled foster child who’s been bounced from home to home, asked the girl for a kiss then forced her to perform oral sex on him before he raped and sodomized her. The boy immediately fled the library following the assault. The girl didn’t tell her mother of the rape until later. The mother sensed something was amiss with her daughter and questioned the girl until she told her the sickening details of what happened. The devastated parents immediately took the girl to the 32nd Precinct station house to report the rape. Police identified the suspect by scouring security video with the library branch manager, who recognized the youth. Police took the youngster into custody when the branch manager called to tell them that the boy showed up at the Schomburg Center for Research in Black Culture around the corner from the library. They found him in a bathroom at the center. The boy is expected to appear in Manhattan Family Court. A neighbor at the Harlem building where the young suspect lived with his father until a few months ago described the boy as a “knucklehead.” “His father never really left the apartment, so the kid was always out on his own. He would just come and go whenever he wanted,” the neighbor said.
