Visitors are being warned they could be cut off by the tide if they try and walk out to a shipwreck off the beach at Brancaster.

Hunstanton lifeboat was launched yesterday afternoon, after reports two children had been seen playing around the wreck of the SS Vina.

Remains of the former target ship lie around the low tide mark.

But powerful currents run between the wreck and the beach and people have drowned after walking out to take a closer look at the landmark, and finding themselves cut off by the tide.

While the lifeboat was on its way yesterday, Yarmouth Coastguards received reports of two boys swimming for shore across a tidal channel.

The lifeboat checked the entrance to Brancaster Harbour and the area around Scolt Head, before the search was called off and it returned to station.

Later last night, the RNLI hovercraft from Hunstanton was also called out to help Lincolnshire firefighters rescue a man trapped in the mud at Holbeach Marsh. The man was freed before it arrived.
