Depends. According to a solicitor quoted in this BBC News article it is apparently entirely possible for the arrest you get de-arrested from to turn up in an enhanced DBS (formerly CRB) check....I probably should have said that 'the authorities' don't have a sense of humour as I am sure the same would have happened in the UK. I work with lots of Americans and of course they have a sense of humour, it's just different.
As has been talked about elsewhere, if you get de-arrested does this cancel the arrest out for problems like yours?
