This post was updated to reflect latest findings about the suspicious substance.

The Council on American-Islamic Relations building in D.C. is currently under evacuation, after the office received an envelope filled with a suspicious substance.

“We’re all outside the building,” says Ibrahim Hooper, CAIR’s National Communications Director. The only exception: the several staffers who remain quarantined inside the building on New Jersey Avenue SE.

D.C. Fire has responded to the scene with hazmat gear.

“We receive threats on almost a daily basis, so it’s nothing new for us,” says Hooper. “But a suspicious substance—that’s new. We don’t normally publicize threats to ourselves but when you have to evacuate, it’s a little different.”

At 3:09 p.m., CAIR tweeted: “Preliminary field tests indicate the substance is not dangerous, letter is now in the hands of the FBI for more extensive tests and investigation.”

CAIR Capitol Hill office was evacuated by police after “foreign substance” received in the mail.
