Navy North Face backpack with orange zipper pulls

I lost my navy North Face backpack yesterday around 3pm near the Bullring Shopping Centre's main entrance on Bull Street in Birmingham, West Midlands. It's a medium-sized backpack in navy blue fabric with bright orange zipper pulls and a small red carabiner clipped to the shoulder strap. There's a tiny embroidered fox patch on the front pocket and a well-worn notebook with my initials inside. It’s a reliable everyday bag I use for uni, and it has sentimental value—my mum bought it for me before I moved here. I really need it back; if you’ve seen it, please get in touch. I’d be forever grateful.
