Bicycle detail

At 12:30pm, I left my black (with blue accents) Raleigh Detour Hybrid outside of 2515 Channing Way so I could attend a meeting in the building. I locked my bike and my helmet (Specialized brand, light blue and gray coloring) with an Abus Plus lock. When I left 2:50pm, the pole where I parked my bike was empty. I searched up and down the street, but my bike was no longer parked anywhere near Channing and Telegraph/Channing and Bowditch. I asked construction workers and people in the area if they had seen my bike, but no one had.
