Because this is coming from someone in another country, I doubt there's a thing the police can do about it really. I would advise no further contact whatsoever with this individual. Keep your eye on Craig's list. This guy may just be blowing and going, but if he posts anything, you can approach it with the administrators of whatever website if posts to. Consider this a hard lesson learned unfortunately. As much education and warning as there is about being careful what you share over the internet/texts/etc., people just don't seem to believe it can happen to them.
