+1 on the advice above. Another scenerio might be that he'a anxious about selling the bike in that area, and feels as though he'd have a better opportuntiy at selling yours.

Years ago while living in Indiana, a guy was stealing bikes from one college campus and driving a couple of hours and selling them (dirt cheap) at another campus. After he sold the bikes, he would then steal more bikes and return to the first school and sell them. Needless to say, the LBS became involved and that is how this person finally got caught. So long story short, be careful!!
