A 13-year-old girl has died after being pulled unconscious from a swimming pool at a special school.
Hayley was once Wales swimming champion in her age-group
Hayley Elizabeth Williams, from Newport, was taken to the University Hospital of Wales, but later died.
An investigation has begun into the incident on Monday at Ashgrove Special School in Penarth, Vale of Glamorgan.
Police said it did not appear the death was suspicious. Ashgrove pupil Hayley was an experienced swimmer and had been Wales champion in her age-group.
Vale of Glamorgan director of learning and development Bryan Jeffreys said: "This afternoon I met Hayley's mum and dad to express our condolences and sympathies, and to offer the Council's support through this difficult time.
