It turns out that bicycles get stolen from right off of Forward Management's property. Or rather, right inside Forward Management Pittsburgh's buildings.
The letter posted to the door reads:
"Dear Residents of [xxxx]
This evening, while doing my laundry, I noticed that my bike that I had locked up to one of the pillars in the basement had been stolen. Someone had cut through the cable lock that I had secured my bike to. While down there, I noticed another bike lock cable that was cut and lying on the floor. I can only assume that someone else's property was stolen as well. I urge all of you to make sure your property is still there, if you do keep a bike downstairs. I have filed a police report. If your property was stolen, you can reference 13209989 when you call 911. The police will take a report for your stolen property. Hopefully this has not happened to anyone else. Signed, Your Neighbor."
