Question

If one of the new breed of (say) litter wardens decides that you have improperly dropped something, and he decides to give you a penalty charge ticket, and you refuse to speak to him and walk briskly away, what can he do about it? Since people, unlike cars, do not carry number plates (at least not for the moment, but nothing would surprise me) how can he establish who you are, to take matters further? I doubt that he has the power to detain you - or has he?

The thought occurred to me after I saw someone drive away from a traffic warden who was only part-way through the process of booking him, and I understand that if the ticket is not put on the car, that's the end of it.

Anyone know for sure?
