A Brooklyn man who had served as a prominent political liaison to the Jewish community for Mayor Bill de Blasio is now behind bars after a sexual abuse conviction.

Aharon Noe immediately began serving 15 days in prison after court officers handcuffed him during his appearance in a Manhattan courtroom.

He was convicted in 2013 on charges of sexual abuse after a woman said he fondled her in a Manhattan bar.

Noe's lawyer criticized the judge and the district attorney for not allowing him to settle his affairs and have a proper goodbye.

Noe donated to the mayor's campaign and also claims he introduced de Blasio to the businessman who helped fund the mayor's trip to Israel last year.

A campaign spokesperson said the mayor will return Noe's contributions.

Noe also must perform 100 hours of community service, and pay a $500 fine.

UPDATE: Noe has been released from Department of Correction custody. This story was originally posted on April 7, 2016.
