A woman has died and a man has been left in a critical condition following the first night of this year's (14) Glastonbury Festival in Somerset, England. A 26-year-old male gig-goer has been left fighting for his life after taking the sedative ketamine just hours after the festival's gates opened on Wednesday (25Jun14). A spokeswoman for Avon and Somerset Police has told reporters the reveller may have suffered an adverse reaction to the drug. Meanwhile, a 67-year-woman died of natural causes at the event. Police say her death is not being treated as suspicious. There had also been 12 arrests as WENN went to press. Acts including Metallica, Kasabian, Arcade Fire, Dolly Parton, Jack White and Lily Allen will perform at the festival from Friday (27Jun14).
