Can a 15 year old get into Leeds fest w/o adult?

[Bella8314]

My friend is 15 and is coming to Leeds festival with a group of us who are 16/17. On the website it says under 16's must be accompanied by an adult but we have no adult... Is it likely that she will be ID'd? She looks the same age as us if not older... Does anyone know how she would get in with us? Is it likely that we will be stopped? 

Any help appreciated, thank you X

ps: we are only going for the day not the whole weekend if that makes any difference.

I imagine it would depend how young she looks. I can't imagine anyone being bothered enough to check unless she looks really young.
