Last night, a reader complained, "A/C/B/D all DOWN tonight because of 'suspicious activity' plus helicopters and NYPD emergency vehicles heading to the scene." It turns out there was an incident at the 116th Street B/C station in Manhattan—a person was struck by a train. NYC Transit Tweeted a little later on, "Update: police investigation @ 116th St cleared, customer deceased. Uptown A & D resume local service only. Expect delays. #ServAdv," and then, "Earlier incident @ 116th St which affected uptown A, B, C & D appears from accounts so far to have been a customer suicide."
