An ultra-Orthodox Jewish man who tried to bribe a young Brooklyn teen to drop her sex-abuse case against a prominent Hasidic counselor pleaded guilty yesterday to bribing a witness in a deal that could let him off with no jail time.

Abraham Rubin, 49, admitted in Brooklyn Supreme Court that he offered the girl and her now-husband $500,000 to leave the country so the case against Nechemya Weberman would be dropped.
