Former Bronx Assemblyman Nelson Castro was sentenced to two years of probation with 250 hours of community service for lying to criminal investigators.

Castro, who had been working as an informant for the investigators in a corruption investigation, claimed he did not talk to the media about his cooperation with authorities — but he did.

Castro said he hopes to carry out his 500 hours of community service teaching citizenship classes at the Davidson Community Center. In court on Thursday, he told the judge he felt shame for having broken the rules and the law.

Castro could have faced more than a year in prison, but Federal Judge Paul Engelmayer took into account the legislator's role as an informant, which helped bring down another former Bronx Assemblyman, Eric Stevenson, on bribery charges.

Castro still faces state perjury charges in Bronx next month.
