Bicycle detail

I was running late on my way to school so I figured I wouldn't have enough time to grab my bike lock. I'd done it a couple times before so I figured it'd probably be fine but when I returned to the bike cage a few a few hours after school ended it was gone and the helmet was left nearby outside the bike cage. It's a black Norco bicycle with a gray triangular bag in the middle of the frame. There might be an orange sticker on the front under the handlebars and a light. There is suspension on only the front with a little zip tie on one side.
