A full scale emergency was declared last night when two girls were reported to be attempting to wade across the submerged causeway from Sully Island to the mainland on the rapidly rising tide.
Customers of the Seashore Grill at Swanbridge saw them in difficulties and rushed out onto the beach and threw buoyancy aids towards them as the two girls lost their footing opn the submerged causeway in the rapidly-rising tide.
Both Penarth lifeboats were launched, Penarth Coastguard officers were tasked to attend the scene at Swanbridge and apparently two rescue helicopters were diverted to the area in what will have been an extremely costly operation.
Both waders/swimmers made it to the shore – but one of the casualties had to be rushed to hospital by ambulance.
Rescue teams said the pair should not have attempted to swim ashore.
