Lost motobike child pink helmet

I lost a pink child helmet for motorbike on Chatham Street, Dublin 2 (on the top of Grafton Street) on Thursday the 5th of November in the evening. It is in a helmet bag grey with long blue strings. It is my daughter's helmet, she really loves it and is crying, I'd love to have it back. It isn't really about the value, it costs something like 60 euros and wouldn't really have a resale value, but I am happy to offer a reward to have it back. Thanks for your help
