Talk to the cops.
Bring your lock with you and some sort of proof or something. Lock the bike up if you see it and just head on over to the cop shop on Mavety. Or, maybe as I suggested in the PM I sent you, ride it over to the cops and explain? I am guessing that you reported the bike at 14 division, right? Vesuvios is 2 minutes away from 11 division on Mavety...
