I've heard the same story from 2 of my regular asian sp's (1 is indy, the other from a small agency).
In both cases, there were 2 guys (the indy didn't have a lobby cam) who came to the apt, took all the money and tossed the place. No one was hurt and I don't think that there were any weapons invovled.
Both girls were pretty shaken up over the incidents.
I think that the key here is that both places advertise on CL.
