What to do if your bike is stolen

Hiya, I'm entirely new to lfgss, and really sorry to have to make this my first post, ..but my self built lo pro bike was stolen last night!

It's a tubular build, with 24' front, so very distinctive looking, in fact it might be the only one on London streets. It's tatty grey, tubular wheel, old school aero seatpost and 3tt bullhorn bars..

If anyone spots it, and can let me know, I would be forever grateful and indebted..I loved this bike so much..

Pics would be really helpful There are a lot of unique bikes around, and quite a few lo-pros. Good luck
