officer confiscated my funds,when codefendant was arrested for having drugs in his possession...

I was arrested along with a codefendant that had drugs in his possession,the officer assumed the codefendant retrieved the drugs from me.The officer confiscated my money,assuming it was drug proceeds. The money in my possession was my "S.S.I"benefit funds for the month. I recently contacted the credit card company that my funds are put on to get a receipt for the withdrawals I made on the day of arrest. On the receipt it states the same amount I had in my possession is the same amount I withdrew from an atm the day of arrest. My question to you,is how can I pursue getting my money back in criminal court?,it proves the money in my possession was not drug proceeds from the codefendant that I was arrested with... Please,to whom this concerns,,share with me a straight forward legal response. I mean no disrespect,but I've been getting some frivolous responses from other attorney-sites.
