Just walk in give them ur full and true name all discription details about what it looks like and ur contact info ofcourse is for them to know how to contact you if it is recovered plus u should've already be talking to the bank and reporting any cards lost/or stolen
Call or go to the station. And make sure you cancel all lost cards
Make a list of everything that was in your wallet. Then go into the police station and file a report. Dont forget to put all your debit/credit cards on fraudulent alert or cancel them if you fear the worst.
