The Guardia Civil have identified the body of a man who was found in Marratxi on Saturday - a 34-year-old Spaniard.
The Judicial Police and the Homicide Squad are both now involved with the investigation, it having been concluded that he had suffered several blows to the head with a blunt instrument.
A couple who were walking their dog raised the alarm at around 10.30am. Their dog ran off and went straight to the body, which was lying in the middle of the Coanegra torrent. Marratxi Police and the Guardia Civil immediately went to the scene.
Investigators believe the body had been there for about 12 hours. Local residents have told officers that they walked by the torrent but didn't see anything strange.
Residents have been asked for security camera images. These may help in identifying any suspicious vehicle or person in the area on Friday night or on Saturday morning.
