stolen 2016 Giant Escape

Our backyard has a 6' high wooden fence and a 6' entrance gate, which is locked with a latch. You must be inside the yard to unlock it. When I went to brew coffee at about 7:30 a.m., I noticed our shed door partially open, and when I looked, I noticed that my bicycle was missing. I assume that someone either climbed the gate and opened it or came over the fence via the alley. It's also possible that entry was gained via the chain link fence of our neighbor's next to our backyard gate, which might have made it easier for them to climb. We have three other bicycles in the shed, but they are all there. The gate was left propped open by our yard wheelbarrow.
