A second letter filled with a powdery substance was sent to Manhattan District Attorney Alvin Bragg’s office Wednesday evening, police said.

The NYPD responded to a call of a suspicious powder in a letter addressed to Bragg in the mailroom of 80 Centre St., police said.

According to Bragg's office, the NYPD determined the powder to be “non-hazardous.”

“We thank our partners at the NYPD Emergency Service Unit and the NYC Department of Environmental Protection for their quick response,” the Manhattan district attorney’s office wrote in a statement.

This is the second time a letter containing powder was sent to Bragg. The first letter that was sent at the end of March was considered a security scare as the prosecutor at the time weighed a potential historic indictment of former President Donald Trump.

Last week, Trump pleaded not guilty to 34 felony counts of falsifying business records related to alleged hush money payments made during his 2016 presidential campaign to two women who claimed to have had affairs with him.

According to the NYPD, the letters remain under investigation.
