Bicycle detail

I locked my bike inside the garage on Wednesday evening, and went to sleep. The next day, on Thursday, I left my house without my bike, and when I got home, I wanted to take my bike out of the garage, but when I opened the garage door, I didn't find my bike. I told my friend that my bike is lost, and we went around the block to search if anyone caught security footage on their cameras, but so far we have found nothing, and have no description of what the thief looks like.
