A human foot was discovered by a beachgoer on Playa d’en Bossa, a popular tourist beach in Ibiza, on Friday 10 October.
The beachgoer secured the foot with a stick to prevent it from washing away before alerting authorities.
The discovery is thought to be a consequence of stormy weather caused by Storm Alice, which recently hit Ibiza and the Balearic Islands.
National police patrols and forensic experts were deployed to the scene to investigate and recover the human remains.
This incident follows a separate discovery of a decomposed body off Talamanca Bay and other similar finds of human appendages on coastlines over the past year.
