A freak gust of wind led to three people being injured after part of a stage collapsed at Bearded Theory on Saturday (16 May).
Those hurt at the event were taken to Derby Royal Infirmary with neck, shoulder and back problems and one suspected broken wrist, reports BBC News.
Speaking about the accident, site manager Sally Booth said: "It's been raining and windy all day but this was a freak gust of wind that was capable of knocking people over."
The winds took part of the roof off of the main stage, damaging the structure and forcing the arena to be closed.
Some people were also treated for shock, but the festival continued with a spokesperson from the event describing the mood of the event as ‘buoyant’, the following morning.
Neville Staples, Hawkwind and The Saw Doctors were among the acts performing at Bearded Theory 2009.
