1980's Ciocc Track Bike

What happened

I locked my bike under the viaduct at the Rogers Park metra station in the morning on my commute to work. When I returned the bike and lock were both gone. No damage to the bike rack. It was a very large and heavy lock that can't be cut with bolt cutters. I have no clue how they could have gotten through it.
