About an hour ago, the police blocked off a section of East 32nd Street just west of the building where I work. They were turning pedestrians back at the yellow tape, and there was vague talk of some kind of threat, maybe at the subway station on the corner (though, thinking back, the blocked-off section didn't seem to include the 32nd Street entrance to the 6 train station). There was no call to evacuate, but with the boss out of town most of us decided to leave the office anyway. I'm home now, but can't find anything on any of the news channels or web sites.
