Another threatening letter was sent to Manhattan District Attorney Alvin Bragg Wednesday afternoon, sources told The Post.

The letter contained white powder and was found in the basement mailroom of 80 Centre Street, according to two sources familiar with the situation.

The NYPD, the Office of Emergency Management, the Department of Environmental Protection all responded to the scene.

The latest threat was first reported by ABC News and confirmed by The Post.

No injuries or illness were reported.

An envelope containing suspicious powder was also sent to Bragg late last month after news emerged his office was on the verge of indicting former President Trump. That powder was deemed not hazardous about three hours after it was discovered, an official said back then.

Trump was charged with 34 felony counts tied to falsifying business records earlier this month by Manhattan prosecutors.
