A Nassau County rabbi was arraigned Friday on sexual abuse charges.

Police say Gary Lieberman, 56, of Far Rockaway, sexually abused a 10-year-old over a period of six months starting in May 2009. According to police, the abuse allegedly happened in a resource room and bathroom at the Hebrew Academy of Nassau County in West Hempstead.

Police say Lieberman told his victim that he should remain silent because no one would believe a rabbi would commit such acts.

Lieberman was fired from the academy in August 2010, the reasons for which are currently unknown. However, school officials say it was not until recently that they learned of the claims.

Parents say they trust the school and administrators' handling of the situation.

Police believe Lieberman may have worked in other schools, and that there may be other victims.

Anyone with information is urged to call authorities at 516-573-4022.
