Police believe they have identified the body of a man found in a reservoir over the weekend.
A member of the public spotted the body in Ogston Reservoir, near Clay Cross, Chesterfield, on Saturday afternoon and raised the alarm.
Officers checked missing person registers but were unable to identify him at the time.
They were contacted on Monday by concerned relatives of a 71-year-old man from Clay Cross who had vanished.
An inquest into the death is expected to be opened this week.
