The grieving family of a missing man drank water from a reservoir where his decomposing body laid undiscovered for half a year.

Glen Godfrey, 38, was first reported missing by his mother Denise, on December 22 last year, 18 days after he was last seen.

Surrey Police assured the family that his body was '100 percent not in the water', saying divers had searched the King George VI Reservoir in Staines, Surrey.

However, his body was discovered in there by a Thames Water employee on May 13, six months after his disappearance.

The reservoir, near Heathrow Airport, is owned by the water firm and supplies drinking water to Londoners across the capital city.
