Bike was stolen sometime between July 24 & Aug 1st 2011 from the rear (facing alley) basement storage room of a building in the middle of the block of 2600 N Orchard st, just west of clark, south of diversey. We have a bike common area in the back of our building which is a 3 flat (storage area is in basement). A number of bikes (probably 8-10 or so) are maintained here and noone locks their bike up (foolishly I followed suit). This area must be entered from a backdoor (which leads outside to a small patio, parking spaces and then the alley) in order to get to the adjacent laundry area which is used by all tenants. There is daily traffic in and out of this area, especially on weekends. Bike was brand new, only rode it once. My best guess is that the door to this area was left wide open at some point and thieves were able to wander in. This room has been burlglarized in the past as people picked the lock, however the landlord does not think this was the case since they have subsequently put a metal cover that covers the space between the door and the door frame where the locks slide in. The door shows no sign of tampering. As noted above, bike has a cable lock wound around the seat pole (I believe it is through the frame as well) which is fastened by a silver master lock that needs a key to be opened. I still have this key. If the bike still has this attached, I could potentially open with the key to prove ownership. The strange thing about the incident is no other bikes appear to have been stolen, and there are at least two others of comparable quality. However, if it was a lone thief, the bike was clearly the newest one and stuck out amongst others due to the bright color, etc.
