A 26-year-old man at Glastonbury has been hospitalised in "life-threatening condition" after taking ketamine, while another festival-goer has passed away of natural causes.
Police do not think that the batch of ketamine had been contaminated and believe that man had suffered an adverse reaction to the Class B drug. A spokesperson for Avon and Somerset Police said that the unnamed victim is from the south east of England and his family have been informed.
An officer tweeted: "Please don't take drugs at Glasto. Ketamine and alcohol dangerously affect your heart and breathing. It can be deadly and you don't know what or how strong it is."
Police also revealed a 67-year-old woman has died at the festival from natural causes. Her death is not being treated as suspicious.
More than 100,000 fans have already arrived at the Worthy Farm site in Pilton, Somerset for the festival, which starts tomorrow. So far, officers have made 12 arrests for drugs-related offences and thefts. Police said crime at the festival was 50 per cent down compared to the same time last year.
UPDATE: The man who had been fighting for his life in hospital has died. A police spokesman said: "Unfortunately the man taken ill after a suspected reaction to ketamine has died this morning. His family are aware and being supported."
