Bike Moved?!

I currently have my bike at the University I'm attending, and in the dorm parking lot, there are a few number of spots, and usually I share a spot with another bike, but this weekend he went home. I went outside to find that my bike had been moved, even though my handlebar lock was on (and working), and she was even in first gear! I know I didn't drink that much last night! But in order to move my bike into this spot, you would have needed the lock to be off, and the clutch engaged. So, I'm wondering if you guys have any idea how that would have happened. There's no scratches, so they didn't tip it over, no skid marks, so they didn't slide it. UGH!!! I'm not even mad... just impressed HAHA!


Any Ideas?

 

The bike can be changed into nuetral without the clutch, so all one would need to do is lift the front wheel (with the fork lock on) and walk the bike where ever they needed to without making a mark. Not so hard to figure out.

 

Or couple guys to lift rear tire and it's movable...
