The Irish Coast Guard has warned the public to "stay back and stay safe" after a child was swept off its feet while walking along the coast.
Shocking moment captured on video in Portstewart shows a massive wave knocking a child off its feet on North Coast.
The video shows a man walking along hand-in-hand with a youngster.
In the blink of an eye, a huge wave crashes onto the coastal path wiping the small child off their feet.
