A former New York City official was charged Tuesday with witness tampering and destroying evidence in a federal investigation that led to Mayor Eric Adams’ bribery indictment. The arrest came amid yet more high-profile departures from Adams’ administration.

Federal prosecutors allege that Mohamed Bahi, who resigned Monday as a community affairs liaison, told a businessman and campaign donors to lie to the FBI in June, and deleted the encrypted messaging app Signal from his cell phone as FBI agents arrived to search his home in July. Bahi had used the app to communicate with Adams, prosecutors said.

Bahi, 40, of Staten Island, was arrested Tuesday and is expected to appear in federal court in Manhattan. Information on a lawyer who could speak on his behalf was not listed in an online court docket.
