A former aide to New York City Mayor Eric Adams is discussing a possible plea deal with federal prosecutors following his arrest last month on charges of witness tampering and destroying evidence, court papers show.

Mohamed Bahi, who served as City Hall’s chief liaison to the Muslim community, was arrested last month as part of a sweeping investigation into Adams and his campaign fundraising that led to the mayor’s indictment on corruption charges in September.

In a court filing made public this week, prosecutors said that conversations were underway with Bahi’s attorney “regarding a possible disposition of this case.” The filing did not elaborate on the nature of those discussions or whether a plea deal would require Bahi to cooperate with federal investigators.

Inquiries to the U.S. Attorney’s Office in Manhattan were not returned. An attorney for Bahi, Derek Adams, also did not return a request for comment.

Adams pleaded not guilty to charges that he accepted bribes of free and discounted overseas vacations and illegal campaign contributions from foreign nationals, including a Turkish diplomat.
