Bicycle detail

I had loaded the bicycle onto the roof rack of my car, which was parked on the street immediately outside the front of my home. I had run back up inside my house to finish eating and to put on my shoes to get ready to head out. I figured it would just be a few minutes and had not locked the bike to the roof rack. Prior to putting on my shoes, I saw the bike still on top of my car and when I glanced up after the bike was gone. I immediately went outside to see if I could spot someone riding away with the bicycle. I quickly canvased the neighborhood for my bicycle by car.
