F.B.I. agents on Tuesday morning arrested Mayor Eric Adams’s former senior chief liaison to the Muslim community on federal witness tampering and destruction of evidence charges that grew out of the investigation leading to the mayor’s indictment last month.

The liaison, Mohamed Bahi, was charged in a criminal complaint in connection with unlawful contributions made to Mr. Adams’s 2021 mayoral campaign, officials said.

Mr. Bahi instructed witnesses to lie to federal authorities conducting the investigation, Damian Williams, the U.S. attorney for the Southern District of New York, said in a statement.

Mr. Bahi, who on Monday resigned from his position as senior chief liaison, was expected to appear in court later in the day.

This is a developing story and will be updated.
