Glastonbury police confirmed the news via Twitter, writing, "Unfortunately the man taken ill after a suspected reaction to ketamine has died this morning. His family are aware and being supported."
"This is another tragic reminder of the risks of experimenting with drugs," a police spokesperson told The Guardian while the man was being treated at the Bristol Royal Infirmary. This marks the second death at the famed U.K. festival, after a 67-year-old woman died in her sleep from apparently natural causes on Wednesday, June 25.
Glastonbury runs through Sunday, June 29, and will feature performances by Arcade Fire, Metallica, Jack White, Lana Del Rey, Skrillex, Dolly Parton, and many more.
