The Police on the Canary Islands have launched an investigation after a human skull and bones were found buried on a beach by a family.
According to Mirror, the horrified family discovered the grisly remains whilst laying down their towels on Saturday.
The remains were discovered at a beach in El Hierro called Arenas Blancas – White Sand in Spanish.
Guacimara Gonzalez, whose brother Joel called police after unearthing the bones, told local press: “We were on the beach as a family when Joel felt something bothering him underneath his towel.
“He thought it was some kind of shell and began to dig into the sand with his hands.
“He dug up a jaw and thinking it was some kind of animal began pulling out other bones, until we realised when we came across the skull that it was human.
“There were also remains of charcoal. We got frightened and called the police.”
The bones, found on Saturday, have been confirmed as human following forensic analysis.
Officials have not confirmed yet how old they are and whether they belong to a man or a woman.
The beach is in the north-west of El Hierro near the remote town of Sabinosa in the municipality of La Frontera
It is described as the only light sandy beach on the island.
It is also near to a popular wine tasting area.
