Old lady gets caught on an escalator

I'm trying to decide if this video of an old lady getting snagged up on an escalator is the real deal, or staged. Almost daily on the air I make a reference to the fact that I just don't believe anything I see or read on the internet anymore. At first glance, it appears to be legit.

An old lady gets her belt caught in the railing part of the escalator (according to the news story anyway). Her friend tries to grab her, to no avail, and she is swooped up the the railing, riding it as if she is on a horse.

Maybe this is legitimate security footage, but if it turns out to be a couple of college guys dressed in drag staging it, let's just say I wouldn't be surprised!
