How do i get my wallet back from stripper?

Went out with some friends the other night and we went to a strip club. Night was going well, when a little brunette asked me if I wanted a private dance. I dont go out often and haven't been to a strip club in 4-5 years so I thought why not? Well I got my dance and she was really good, all over me, Im sure we broke a few laws but after I left the room and tried to buy a beer but my wallet was gone. I went to the back and told the bouncer, he let me check and it wasn't anywhere in the back. I saw the dancer and asked her, she told me she hadn't seen it, but she had a really tiny purse and I could see the shape of my wallet threw it. I confronted her and next thing you know, Im outside on my @ss without a wallet. I called the police, well they basically laughed at me and flirted with her and did nothing. I need this wallet back, lots of papers and cards I need, there was 400$ in it also but i don't care about the money, just need the rest back. What do i do?
