Two teenage girls who were reported missing by their mother in Hunstanton were found after a Royal National Lifeboat Institution (RNLI) hovercraft was launched.
The two 13-year-olds had been playing with an inflatable toy shark before they disappeared on Tuesday at 6.05pm.
As the hovercraft was searching for the pair, they were sighted by RNLI crew from the boathouse at 6.25pm, about half a mile to the East walking towards the shore.
They were then handed over to the care of the local police who were helping with the search.
A spokesman for RNLI said: “Our advice to visitors is do not take inflatables to the sea, however tempting. Offshore winds and tides are a recipe for disaster. Enjoy your holiday and stay safe.”
Later in the evening, a hovercraft crew advised a group of people swimming off of Hunstanton sandbanks about the turn of the tide.
The spokesman said: “Do not venture out onto the flats or banks at Hunstanton, Heacham or Snettisham.
However tempting, tides in this area go out over a mile on big ebbs, and where the tide turns the tidal currents are very strong.”
