I had a bike stolen and filed a report, and I also posted detailed signs in local shops. I also reduced the size of the sign and carried one in my wallet. One shop reported the bike being brought in and I told them to call the cops while I raced over to claim it, showing the cop my wallet sign (with serial number of the machine and the police report number), and he let me take my bike while he was arresting the suspect.
