Bicycle detail

I came outside and went to the place behind my apartment building where I usually have my roommate and I's bikes locked up, and noticed that my e-bike was missing. When I took a closer look, I saw that our chain-link chain had been cut (the cut piece was left at the scene), both of our bikes had been unlocked because of this, and mine had been taken. Although my roommates bike was also unlocked, it had not been taken. Unfortunately, there are no cameras on the back of our apartment building. The battery was NOT in the bike when it was stolen, so it has an open gap in the frame where a battery would go.
