Definitely file a police report and give them the serial number. Also check with your tenant insurance/home owner insurance policy, it may be covered.
I've seen some bikes in the last few years where the s/n was simply put on a sticker stuck to the frame. Not sure if the s/n is stamped or imprinted into the frame in a more concealed location.
