When Joel Engelman was 8 years old, he says, he was called from his Hebrew class to the principal's office at his Brooklyn yeshiva, a Jewish religious school. His parents had recently told Rabbi Avrohom Reichman that their son had been abused by an older boy at the school, he says.
But he says the rabbi was not offering to help that day.
When Engelman arrived at the principal's office, he says, Reichman told him to close the door. He told the boy to sit on his lap and began swiveling his chair back and forth, Engelman says. Reichman then touched him, moving from his shoulders down, Engelman claims.
The same kind of abuse went on twice a week for several months before he left the school, Engelman claims in a civil lawsuit filed against the yeshiva, the United Talmudical Academy.
For more than 10 years, Engelman, now 23, kept what he says happened to himself. He left the orthodox community and found new friends. It wasn't until about two years ago, when he says he heard that other boys allegedly had been abused by Reichman, that he tried to do something about it.
But Engelman says the response from religious leaders has been just as disturbing as the alleged abuse. He claims the school's religious leaders told him not to go to the police, and promised to remove Reichman from the school, which they did for a few months.
"They kept telling me, 'Don't go to the police, don't do anything. We've dealt with this before,'" with other teachers, he said. "It really shocked me."
A few days after the statute of limitations for Engelman to file a civil or criminal case against Reichman for abuse passed, the school reinstated the rabbi, the lawsuit claims.
Engelman's is among a handful of publicized cases of alleged abuse within the insular Orthodox Jewish community. But alleged victims and their advocates say it is far from an isolated instance.
The Brooklyn district attorney's office, which last month announced a hotline for alleged Orthodox sex abuse victims, says it has 19 active cases of alleged sex abuse in the borough's Orthodox Jewish community. And advocates say the problem extends beyond Brooklyn.
"If you're a pedophile, just go to one of the orthodox communities. You're probably safest there," said New York State Assemblyman Dov Hikind, himself an Orthodox Jew. "It's sad for me to say that, but it's true."
When Hikind broached the subject of sexual abuse on his weekly radio show last year, he said he was "inundated" with calls from alleged victims from the United States, Israel and parts of Europe.
ABC News has spoken to Orthodox Jews who claim they were victims of abusers in New York, Baltimore and Illinois, who shared stories of alleged molestation followed by what they described as hostility from community leaders when they sought help.
Hikind says another of Reichman's students, who has not come forward publicly, claims he was abused by the rabbi as a child.
"A lot was attempted, a lot was tried" to remove Reichman from the school, he said. "He is unfortunately still in the classroom."
A lawyer for Reichman, Jacob Laufer, said the rabbi "vehemently denies" that he abused any students. He said the school conducted an investigation into Engelman's claims and found that they were "without merit."
