Black Samsonite suitcase with red luggage tag

I lost my black Samsonite suitcase yesterday around 3pm near the Europa Hotel on Great Victoria Street, Belfast. It's a medium-sized polycarbonate case, a bit scuffed along the bottom, with a bright red luggage tag looped over the handle. There's a blue TSA lock on the zipper and a small dent on the front corner. Inside are my clothes for an important interview and a lightweight gray scarf my grandmother gave me, which makes it sentimental. It’s the only bag I had for this trip, and I’d really love to get it back—if anyone picked it up, I’d be grateful to hear from you.
