A woman in her 30s has died on a family holiday after falling overboard from a boat in Lough Erne, County Fermanagh.
Police received a 999 call at about 01:15 BST from a man who said his wife had fallen overboard from a rental boat moored at Devenish Island.
They believe the woman slipped as she was securing ropes to a jetty. Her body was recovered shortly before 02:00 BST.
The County Donegal family had rented the boat and two young children were asleep on board at the time.
An investigation is under way and a post mortem examination is due to be carried out.
Lough Erne, which stretches for 55sq miles, is a popular tourist destination with more than 150 islands.
“(The victim’s husband) had tried to go into the lough to find his wife, but unfortunately he could not get her,” PSNI Ch Insp Clive Beatty told the BBC’s Good Morning Ulster programme.
After the emergency call was received, two ambulances were dispatched as well as fire service, police and coastguard teams. Police searched the water and her body was recovered.
Mr Beatty said police believe the woman went to check the securing of ropes against a jetty before she went to bed for the night “and at that time she slipped and fell off the back of the boat into the water”.
“We performed CPR (cardiopulmonary resuscitation) ourselves and transferred then to the ambulance who continued to conduct CPR until 02:57 when the woman was pronounced deceased at the hospital,” said Mr Beatty.
Expressing his condolences to the woman’s family, Fermanagh and South Tyrone MP Tom Elliott said Lough Erne was a “dangerous place” and called on people to be careful on the water.
