If it happens as you said, and obviously there is a video, I don't think a theft charge would stick (Keeping in mind that keeping lost property that doesn't belong to you is larceny, but change in a machine?) I think you should speak with a personal injury/civil rights lawyer about the detainment. It sounds like it may have been unlawful.

This is a purely criminal law issue. I have edited the practice area you selected so that you will receive responses from lawyers who practice criminal law and will be able to give you a much more reliable answer than I could.
Yes, you can be charged with theft; however, that doesn't mean you don't have any defenses so hire a lawyer to help you
