Members of the public are being advised by Ports of Jersey to keep well away from it.

Ports officials said they were “currently assessing the damage to the groyne and will be taking appropriate measures.”

“Until that time, for safety reasons, members of the public are being asked to not access the area and warning signage is being put up.”
