The first question is why was it confiscated? Once you answer that, then there can be a resolution. If you think it was taken for not a valid reason. You can file a police report.
I would call the police and ask for help, unless it was fake. If was fake you won't get it back.
Sounds like a Management or Owner/ Operator question, or a legal issue, suggest you try contacting them directly. Not through here.
