I've reported him for fraud and theft this morning and I am awaiting a call from the police in the coming days to get more information from me.
Well done. Do you happen to know M4v3rs postal address, or did you just state his name, country and photograph?

Edit: Did you report him to the polish police or the police of your country?
So, good luck and keep us updated! As far as the police thing is concerned, they will simply not do anything at all because there is no "public interest".
Probably yes as long it is only one case. However things may look differently, if several people file a police report. And even if they do not pursuit the case any further, M4v3rs name will from now on be on records.
