Thank you for responding to me, I now have a new question, If the said item that was taken for me is proven that it was not even stolen, and that had made a mistake in the first place, because they failed to even check if the item was stolen to start with, what would this outcome be?

I don't have enough facts, but if the item is yours and you obtained it lawfully, the police cannot keep it. Contact an attorney to give him/her all the facts, documents, etc., for advice on recovering the item.
