Bicycle detail

On my way to work I went downstairs to the back area of my apartment building to take my bike to work around 3pm Saturday 8/17/19 to discover it was vanished from where I had locked it to a thick wooden fence. The last time I saw it I was coming back from work the previous night/ same day at 1am, locked where I put it. The key required cable lock I used that was likely clipped when stolen came with the bike and would lodge itself underneath the seat inside the frame for easy storage. I have the key if anyone needs further confirmation that a bike is mine. The scene left no traces or marks and my neighbors nearest to the wooden fence werent home when the incident occurred.
