A 27-year-old Whitestone man who teaches at a Bronx high school was arrested on Thursday on attempted rape and other charges after he tried to meet up with a 14-year-old girl who actually was an undercover cop, authorities said.
Jonathan Blum, a history teacher at DreamYard Preparatory School and basketball coach in Queens, was busted after he posted an ad on Craiglist looking for a young teen, student and/or young girl who would be interested in fooling around with a licensed real teacher, according to the district attorney’s office.
An undercover NYPD vice detective answered the ad and Blum started exchanging emails and text messages with the detective, who he believed to be a 14-year-old girl.
Those messages, sent back and forth between mid-April and mid-May, were sexually explicit, prosecutors said. After several exchanges, Blum wanted to meet up with the supposed teen and, according to police, arranged a rendezvous at a location on Northern Boulevard in Flushing. But instead of finding the girl there, Blum found himself in handcuffs at about 5:15 p.m. on Thursday.
Blum has been charged with attempted rape, attempted criminal sex act, attempted endangering the welfare of a child and attempted disseminating indecent material to minors, according to authorities. He is currently being held pending arraignment in Queens Criminal Court.
According to the Department of Education (DOE), Blum has been a teacher at DreamYard Preparatory School, located at 240 E. 172nd St., since April 2011 and has no disciplinary history with the department. He has been reassigned away from the classroom pending the resolution of his case.
“While this alleged behavior is not school-related, it is incredibly disturbing,” DOE spokeswoman Devora Kaye said. “This individual has been immediately reassigned away from the classroom, and he will not be in contact with any students.”
If convicted of the criminal charges, Blum faces up four years in prison and would have to register as a sex offender.
Any parent whose child has conversed with the email address email@example.com, which Blum used in his exchanges with the undercover officer, and has concerns is encouraged to call the Queens district attorney’s office at 718-286-6260.
