RNLI is urging people to be aware of the potential risks when walking on beaches
Two walkers have been rescued by Dun Laoghaire inshore lifeboat, after they were cut off by a rising tide.
The pair raised the alarm by mobile phone and kept trying to walk towards shore.
However, when they found themselves waist deep in the sea around half a mile off Sandymount, they returned to a sandbank to await rescue.
The coastguard helicopter based at Dublin Airport was also dispatched.
Both the chopper and the lifeboat arrived to help the pair at 12.15pm. One of the walkers was treated for a minor injury.
Robert Fowler, Deputy Launching Authority with Dun Laoghaire RNLI, has urged walkers to be aware of the risks when on beaches, with today's incident the third of its kind so far this year.
“Walking on our local beaches is very popular but care is needed in respect of the state of tide that is constantly changing," he explained.
“From low-tide to high, water-level can become several metres deep in the course of a long-walk at the waters’ edge," he added.
