North Norfolk-based music promoters Baselogic Productions have gone in to voluntary administration after an event they were organising was shut down amid fears over crowd safety.

The two-day Bloc Festival, which was being held at London Pleasure Gardens, was closed by organisers in the early hours of Saturday, July 7, shortly before American rap star Snoop Dog was due on stage.

Baselogic Productions, trading as Bloc, was registered at an address in Thornage Road, Letheringsett, Holt, until July 16.

Jamie Playford, of Norwich-based insolvency practitioners Parker Andrews, has been appointed administrator of the company.

In a statement, Baselogic Productions said: 'The team are working hard with the administrators to investigate the issues that led to the closure of the event and people will be updated as and when we have new information.

'We ask that you allow the administrators time to conduct a thorough investigation so we can establish the facts.

'Once again we would like to apologise for all of the frustration and disappointment this situation has caused and thank everyone who has supported the team over the years, your continued support means so much to us.'

The annual festival started in 2007 and was due to take place in London for the first time

A message on Parker Andrews' website said an investigation into the facts leading to Base Logic Productions and the administration would be conducted immediately

Mr Playford added: 'It is important that we understand the full facts including what funds will be available to creditors and ticket holders and to ensure the information we provide about the next stages of administration is clear and concise.'

Norfolk Trading Standards issued advice for Bloc Festival ticket holders seeking a refund this week. It said: 'Consumers who purchased tickets on credit or debit cards can find out more about the possibility of obtaining a refund by Chargeback on the Adviceguide website. Those who purchased tickets via other payment methods and believe they are due refunds should look to make contact with the administrator.'

It was reported that there were chaotic scenes at the opening night of the Bloc Festival, with police called in to help evacuate thousands of people from the site.

A second day and night of music, which included performances by Gary Numan and Orbital was also cancelled.

A Metropolitan Police Spokesman said: 'It was the organisers' decision to close the event due to fear of overcrowding. Police officers attended to ensure safe transit of people from that location.'

A message printed on the Bloc website shortly after the event said the festival was closed due to crowd safety concerns,

It read: '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.'

The hashtag #bloc has been trending on Twitter, with many people angry about the cancellation of the festival.
