The FDNY is investigating suspicious white powder found at the office formerly used by Aaron Schlossberg, the attorney who won viral infamy for his xenophobic rant and threats against Spanish-speakers at a midtown Fresh Kitchen.

The "hazardous material" was spotted at 275 Madison Avenue at 3:30 p.m. on Thursday, according to officials, and the Fire Department was still at the scene more than an hour later. A spokesperson for the FDNY said they are currently evaluating one person, but that there has not been any hospitalizations so far.

Schlossberg was booted from the midtown co-working space because "his actions [in the video] were inconsistent with our community and rules," according to Hayim Grant, the president of Corporate Suites, which operates the co-working center. Earlier this week, in Manhattan Civil Court, Schlossberg reportedly complained to a court officer that he was being harrased, after another attorney shouted, "It’s the racist lawyer! Fuck that guy!"

On Tuesday, Schlossberg addressed the incident for the first time in a statement shared from his law firm's Twitter account. It reads:

To the people I insulted, I apologize. Seeing myself online opened my eyes—the manner in which I expressed myself is unacceptable and is not the person I am. I see my words and actions hurt people, and for that I am deeply sorry. While people should be able to express themselves freely, they should do so calmly and respectfully. What the video did not convey is the real me. I am not racist. One of the reasons I moved to New York is precisely because of the remarkable diversity offered in this wonderful city. I love this country and this city, in part because of immigrants and the diversity of cultures immigrants bring to this country. Again, my sincerest apologies to anyone and everyone I hurt. Thank you.
