stolen 2003 Gary Fisher Wahoo

I arrived at City College of San Francisco Downtown campus @ 8am. Lock my bike on a bike rack using my combination lock in front of Cole Hardware Store at 4th st between Market st. and Mission st. on 12/11/2012. I soon thereafter, return to the location to find my bike missing along with the combination lock. I ask the surrounding businesses including Cole Hardware store, City College of San Francisco Downtown Campus, and City College of San Francisco Book store, if they had seen what happened to it. Apparently no one had seen anything. After i'm done questioning the stores, I go to the local san francisco police station to report that it had been stolen. Silver Series aluminum
