2017 Schwinn Schwinn circuit, (red,black, and white)

Recently I moved into the apartment building bitter Lake and we were told that we could not keep our bikes in our unit and that there was a bike Room. I brought my bike down to the bike Room a second week that I moved in everything was fine and then bikes started to be stolen, the maintenance man asked me to check if my bike was stolen in I told him that my bike could not have been stolen because I have a lock on my bike and the bike that I had did not have a seat on it as well as I deflated the tires so that it will be hard for anyone to steal the bike. I guess that didn't help nor did it stop the person from stealing my bike this had to happen some between the 4th and the 11th of June. The last time I check on my bike was before the fourth of June and it was still there. When I checked on the bike yesterday June 11th 2019 my bike was gone. My bike is a newer Schwinn model no older than 2017 specifically it is a men's circuit Schwinn, it is red black-and-white with red black-and-white stock tires ,everything on the bike is stock nothing has been modified except the seat which I still have, Because I usually remove the seat when I lock up the bike . I never took the time to write down the serial number of this bike Because it was so new I only wrote it a few times. The bike is in great condition. This bike was stolen out of the bike room.
