Bike was locked to the fence outside the bedroom in our garden level apartment (newer u-lock with flat key). Around 4:00 a.m., I woke up to what sounded like someone pulling on the fence outside. A few seconds later, I saw the motion-detector powered light on the side of our building (leading to the back alley) go on. I ran upstairs to check on the bike, thinking that it had been stolen, and was shocked to see that it was still there. I didn't go outside to fully inspect it, but it looked like the lock was still attached and all was well. I waited upstairs and watched the bike for 5-10 minutes to see if the thief would try again. I then went back downstairs to try to go back to sleep. About 10 minutes later, I heard the door in our gate slam and various car noises and music. When I went outside the next day to bike to the gym, the bike was gone. The fence the bike was locked to had been cut and the bike stolen. The bike was less than two months old.
