Blue Giro road bike helmet with white accents

I lost my blue Giro road bike helmet yesterday around 3pm near Market Square tram stop on Maid Marian Way in Nottingham, East Midlands. It's matte cobalt blue with white Giro branding and size L, with an adjustable rear dial and removable padding. There's a small dent on the outer shell near the Giro logo and a lime-green reflective sticker on the inside of the strap. This helmet is my daily ride shield and holds sentimental value because it was a gift from a cycling club mentor; I really need it back if anyone found it. If you found it, please get in touch—I'd be grateful to get it back as soon as possible.
