Panic at 35th St.
They just quarantined the building at 35th St. Seems the Superintendent's people opened the mail and found white powder in at least one envelope. CFD is arriving along with CPD Haz-Mat team. Persons inside the building are not permitted to leave. People outside are not permitted in. And before you start making the "powdered" v. "creme filled" wisecracks, remember ... ah screw it, go ahead and crack wise. We're the police after all.
UPDATE: 0945 hours - HQ is now open. The mysterious white powder has tested negative for known pathogens like anthrax. No results on whether it might be powdered sugar, Sweet & Low or Equal. Rumors abound though, that the bag upon which the powder was discovered bore the fragments of the words "...unkin" and "...onuts." Area 1 is investgating. That is all.
