The more I read about this, the bigger the shambles it seems.
From what I can piece together, the ticket entry scanning system broke down entirely. So tickets were not being checked properly, leading to people without tickets gaining entry.
Upon gaining entry, each of the stages had a tiny bottleneck system of entry/exit causing more queuing/ overcrowding.
It sounds like it was the correct decision.
NO apology seems to be forthcoming from organisers. The only statement from them says:
By now everyone will have heard that Bloc 2012 was closed due to crowd safety concerns.
We are all absolutely devastated that this happened, but the safety of everyone on site was paramount.
Given the situation on the ground, we feel that it was the right decision to end the show early.
Bloc will not open on Saturday 7th July so please don’t come to the site.
Stand by for full information on refunds.
I feel so sorry for everybody who was there, but especially those who travelled from around the world
