'No Dangerous Substances' In Envelopes Found At 26 Federal Plaza: Mayor

NEW YORK CITY — Employees containing white powder found at 26 Federal Plaza in Lower Manhattan on Thursday did not contain any dangerous substances, officials said on Friday.

In an 1010 WINS radio interview, Mayor Eric Adams said there were "no dangerous substances" used in the incident.

"We are going to make sure the person responsible will be brought to justice," Adams added.

Two people who were exposed to the powder are expected to recover.

The incident happened just before 4 p.m., the FDNY said. The incident prompted the building to be evacuated.

According to ABC News, the substance is believed to be boric acid, which is commonly used in pesticides and other chemicals.

The NYPD and FDNY Hazmat teams are investigating the incident.

ICE detainees were moved to a different location during the emergency response and evacuation, according to PIX11 News.

On Tuesday, A U.S. District Judge ordered the Immigration and Customs Enforcement to improve conditions at a holding facility at 26 Federal Plaza.
