Three people reportedly fell ill after coming in contact with a suspicious white powder with a sweet scent which was sent in an envelope Monday to a Brooklyn, New York Supreme Court.

Around 12:30 p.m., a woman called police, saying she was an assistant to a judge on the eighth floor of the Kings County Supreme Courthouse, and had opened an envelope that contained the powder.

The woman and two others were evaluated by emergency medical personnel after they began to feel sick, the New York Post reported.

The New York Daily elaborated on the incident:

Floors 8 and 11 were on lockdown as the NYPD’s Emergency Services Unit and the city Department of Environmental Protection investigated. There were no evacuations, but access to those floors remained limited more than two hours later.

“It was an envelope that somebody opened and they were concerned,” FDNY Chief Russ Regan said, adding nobody is “symptomatic.”

Regan said the hazmat crew got “zero readings” on the powder and have turned the substance over to the Emergency Services Unit, who will bring it to a lab for testing.
