the security incident appears to be a legit citizens arrest of a suspect, most likely within sight of real cops and CCTV. These all now get logged and have to be accounted for, you can often even look on the old bill website for the area where the festival occured and there will be a list of incidents posted under freedom of info section.
The lad who was attacked was not set upon *within* the arena (its clearly full of rentaguards and cops from your own description!) but in campsite/carpark outside.
Alas this is not the first such incident I’ve heard of nor is it a “Northern” thing; there have been similar attacks at festivals in Essex, Suffolk and Reading over the years.
Tends to be angry lads on too many roids who’ve maybe been turned down by a girl or are just going through mood swings and are looking for an easy victim.
They don’t of course beat up loads of people or start mass fights like some scene out of Game of Thrones (b/c security is well aware to this particular risk) but just pick one or two at a time per event in less policed areas.
So take care of your personal safety, wherever you go..
