Matthew Parrott, a 48-year-old man with a medical condition, was unfairly removed from The O2 Arena during a Glass Animals concert after staff mistook his stumbling for intoxication. Parrott, who has faced health challenges since a bone marrow transplant, expressed his frustration after being denied entry back to the venue despite his explanations. The O2 has since apologized, refunded his tickets, and committed to reviewing staff training to prevent similar incidents.
