A coastguard rescue team has warned the public to stay out of a large cave in a cliff on a Cornwall beach after rocks started to fall inside.

Portreath Coastguard Rescue Team were called to the caves on Portreath Beach late on Monday evening after a member of the public reported an "active cliff fall" on the beach.

When they arrived they found the fall was actually in a horizontal passage leading into a mine for the purposes of access or drainage, known as an adit.

As small rocks and and debris were still falling the team decided to cordon off the entrance of the cave to warn people not to go inside and take unnecessary risks.

They also decided to inform Cornwall Council about the fall so further assessments could be carried out. They tanked the person who made the call.

Posting on their Facebook the rescue team said: "The team were tasked this evening at approx 21:30 to reports of an active cliff fall within the caves on Portreath Beach.

"Once on scene it was discovered this was a small fall from the adit within the large cave.

"Due to the fact that some small rocks and debris were sporadically falling it was deemed necessary to fence off the cave with barrier tape as a precaution.

"The team then suggested that Cornwall Council be made aware to carry out further assessments as and when required.

Please abide by the cordon and steer clear of the cave to avoid any unnecessary risks.

Thank you to the caller for raising awareness of this incident.
