A temporary cordon has been put in place after a deep sinkhole appeared on a beach.

RNLI Lifeguards at Seaton Beach, whose patrols began there at the weekend, were the first to report the hole in the sand, which appeared next to a new slipway and gate installed recently by Cornwall Council.

The local authority said: “A temporary cordon has been installed after a sinkhole emerged at Seaton Beach. Investigation works will be carried out at the site.

“In the meantime we urge beach users to respect the cordon for their own safety.”
