An 18-year-old man had to be rescued from a hole he dug on the beach after it collapsed on him.
Emergency services were called by the coastguard to Fistral Beach in Newquay at 5.30pm on Thursday.
They found the man trapped in a hole he had dug in the sand after it fell in on him, Devon and Cornwall Police said.
The force said that “friends and beachgoers all worked together to dig the man to safety”.
He was allowed to return home after being checked over by medics, Newquay Community Fire Station said on Facebook.
“This could have easily resulted in crushing or suffocation,” they wrote.
“Please don’t dig huge holes in the sand, sand is partial to collapse and the dry weight is around a ton per metre cubed.
“You wouldn’t dig a hole in the garden and let your children climb in; please don’t do it on a beach either.”
