The RNLI has released a video of its part in yesterday's sea rescue near Rhosneigr. Volunteers from Trearddur Bay launched their lifeboat in rising tides and rough seas, after receiving reports of people in trouble in the water.
Two people were winched from the sea by a RAF Sea King helicopter, while the lifeboat was tasked to rescue a further young man who had been washed onto rocks.
The rising tide and rough conditions hindered the rescue attempts and one crew member jumped into the sea to swim to the rocks to help the teenager until the lifeboat could get closer.
