Lost black Eastpak Backpack at Dublin Tourism Office (upstairs at cafe)

I lost a black backpack at the St.Andrews Church in which the Dublin Tourism Office is, upstairs at the cafe called "Finn MacCools" The Backpack contains a Lenovo X200 notebook, 2 chargers and a newspaper. I would be very happy to hear from anyone who might know where it is, it would save me 2 months of work! I pay a decent amont of money for the person who would be able to get it back to me!
