The unnamed man, believed to be from the south west of England, had been taken to hospital in Bristol yesterday where his condition was described as "life threatening".

A tweet from Glastonbury police confirmed the death earlier today.

"Unfortunately the man taken ill after a suspected reaction to ketamine has died this morning. His family are aware and being supported."

This marks the second death at Glastonbury 2014 following the passing of a 67-year-old woman on the opening night of the festival. Her death is not being treated as suspicious.
