An associate principal at a top Jewish private school in the Bronx was busted for allegedly manipulating a 14-year-old student into sending nude photos of himself, feds said.

Rabbi Jonathan Skolnick, who worked at Salanter Akiba Riverdale Academy in Riverdale, was arrested on Friday at his Bronx home on charges that include child enticement and possessing child pornography.

The middle-school administrator allegedly posed online as multiple teenage girls to communicate with the 14-year-old starting in March.

“Typically, one ‘girl’ would introduce him to the next ‘girl,’” the FBI said in the complaint. “The communications with each ‘girl’ were platonic in nature at first and then became sexual.”

The teenage victim was then coerced into sending sexually explicit photos of himself in June to fake email addresses, such as girlwholikesyou@protonmail.com, according to the complaint.

The supposed “girls” would also exchange photos with him, claiming snaps of naked women were of themselves, feds said.

When the boy stopped responding, Skolnik adopted a bogus phone number pretending to be one of the girls and sent messages that “became increasingly threatening in nature.”

Then the teen got scared the person he’d been exchanging photos with would make them public, the feds said.

“Apparently you don’t care who knows,” one message allegedly threatened.

Skolnick admitted to the depraved scheme when he was busted, telling authorities that there were “approximately 20 to 25 victims,” most of whom were minors, according to the complaint.

In a letter Monday to parents, school principal Rabbi Binyamin Krauss said that Skolnick had been terminated and warned that other students may be victims of the scheme.

“We have reason to be concerned that SAR students may have been victims or potential victims and we are asking you to share any information you have with law enforcement as they continue to conduct their investigation,” the letter said.

If convicted of the charges, Skolnick faces up to life in prison.
