Two individuals, one alive and one already dead, were picked up by the Marine Rescue service about 19 miles out to sea off Málaga and transferred to the port.
The two individuals, Spanish nationals aged 22 years and 27 years, were apparently out on jet skis when one of them broke down. They carried on their journey on board the functioning machine but that one also broke down.
The 22 year old was injured and was taken to the Carlos Haya hospital in Málaga for treatment before later being discharged.
The Guardia Civil is investigating the incident.
