Britain's Glastonbury Festival has been marred by a second death just hours before the first official performances kicked off on Friday (27Jun14). A 67-year-woman died of natural causes at the event shortly after the gates opened at the site in Somerset, England on Wednesday (25Jun14), and a male reveller was later admitted to hospital in critical condition after suffering an allergic reaction to the drug ketamine. The 26-year-old man died in hospital on Friday morning (27Jun14), shortly before the festival got into full swing with performances from acts including the Kaiser Chiefs, John Newman and Blondie. A statement from local police reads, "A man has died following a suspected reaction to ketamine. The man was taken ill overnight on Wednesday into Thursday and was taken to the Bristol Royal Infirmary. Unfortunately he died earlier today (Friday)... His death is not considered suspicious. At this stage we believe this was an individual reaction to ketamine and was not from a bad batch of the drug." The festival, which runs until Sunday (29Jun14), is also set to feature performances from Arcade Fire, Metallica, Kasabian, Lily Allen, Ed Sheeran and Jack White.
