The National Police are investigating the discovery on Friday of a body in the reeds in a stream near avenida de Juan Carlos I in Jerez de la Frontera, Cádiz province.
The deceased is a 60 year old man with mental problems who was reported missing by relatives on Friday morning.
Initial indications tend to discount a violent death, the theory being that the man became disoriented and fell down the four metre high embankment into the stream. The stream at this point is about 50 centimetres deep.
