Found orange cycling helmet near Cardiff Bay

I found a bright orange Giro Atmos road cycling helmet this afternoon around 3:50pm on the Cardiff Bay promenade near Mermaid Quay. It's a medium size, with white vent covers and a reflective strip along the back. There’s a small scratch on the left rear edge and the inside padding is a bit damp from today’s drizzle. The black chin strap is intact and adjustable, and the Giro logo is clearly visible on the front. It looks recently used but still in good condition, and I’d love to get it back to its owner if you can confirm the size and any marks.
