At most concerts, fans are simply put back into the crowd when they reach the security pit below the stage.
But at Reading, they will be ejected from the arena and forced to walk back to the main entrance to get back into the site.
“Reading Borough Council Health & Safety team consider it quite dangerous and we will endeavour to try and limit the amount of times people will do it,” Mr Benn said.
“They won’t be ejected from the festival but they’ll be ejected from the arena. What that will result in is probably around a 20-minute delay before they get back into the arena. It will certainly delay their ability to get back in to watch the band.”
