Sorry to hear this Matty. I had a bike stolen from my car years ago. I lived in South Jersey at the time. I called the police out and gave them the serial # and they filled out the report and all. What they said to me next was truly depressing. They said a lot of bikes get stolen and they typically don't have time to chase serial numbers down....they have more important things to worry about than stolen bikes.... :-(
Hopefully your PD has a better outlook on the situation.
Needless to say, I never saw my bike again. :-(
My insurance company was helpful. They cut me a check less my deductible so I was able to go out and get something.
I hope they catch the DB and get your bike back man.
