Law enforcement officials confirm that a suspicious powder sent to the Manhattan district attorney's office in Lower Manhattan, marked "Alvin," was nonhazardous. The envelope was delivered by the US Postal Service to the mailroom at 80 Centre St. on Friday. NYPD officers arrived on the scene after a 911 call reported the incident. Although there were no injuries reported, the timing of the incident raises questions, as Bragg's office has been presenting its case to a grand jury considering the indictment of former President Donald Trump over hush money paid to porn star Stormy Daniels during his 2016 campaign. Coincidentally, bomb threats were called in at the courthouse earlier this week, which disrupted the proceedings, but it is unclear whether the two incidents are related. Trump threatened Bragg with "death and destruction" if he is indicted, and last week Bragg warned Trump supporters not to threaten or intimidate his office. The office assures everyone that they have increased security measures, and officers have been reminded to stay vigilant and maintain situational awareness.
