Bicycle detail

Some time between 3/6/15 and 3/21/15, a person entered our condo building. There were a number of bikes stolen over the course of approximately one week during the week of 3/16, and on 3/21, I discovered that mine had been stolen as well. My bike was locked in a storage closet on-site. Door to storage closet was not broken, so someone likely had a key for it. There are only a few people with that storage closet key. I am reviewing film footage from our building's security camera now to see if I can ID the perp, and get a good picture. We have identified several people coming into our building between 2am and 6am on multiple nights casing for bikes to steal. I'm just not sure yet which person stole mine. I will update this report as I find more information.
