56-year old Gary Lieberman of Far Rockaway is charged with two counts of sexual abuse. He has pleaded not guilty.
Lieberman was arraigned Friday, and was released on $100,000 bail.
He is due back in court Oct. 22nd and faces up to 14 years in prison if convicted.
Nassau County Police say the incident occurred in a learning resource room on the second floor of the Hebrew Academy of Nassau County, and additional inappropriate conduct occurred inside the restroom of the school.
Lieberman allegedly told the victim that if he tells anyone about this they would not believe him because he is a rabbi.
A school official notified police about the allegations this year.
Police say the alleged abuse occurred between November 2009 and May 2010. His employment as a religious teacher at the academy in West Hempstead was terminated in August 2010.
But police say he may have continued teaching at other private religious schools.
They're asking any other possible victims to notify the Nassau County Police Special Victims Squad at 516-573-4022.
