A rising swimming star has died in bed at home in Greater Manchester just hours after she won her latest accolade.
Schoolgirl Chloe Waddell, 16, went into cardiac arrest on Sunday morning and despite efforts from an ambulance crew to save her she was pronounced dead in hospital.
Tipped to be part of the GB squad for the 2016 Olympics in Rio de Janeiro, Chloe had been presented with an Outstanding Achievement Award for swimming just the day before.
Her parents, David and Fiona, who found her unconscious and tried to revive her at their home in Timperley, said they were "devastated".
"Chloe was exceptionally outgoing, extremely popular and had a wonderful smile - she was always smiling at all times and she had a kind word for everybody at all times," Mr and Mrs Waddell said in a statement.
"There was never a dark day for Chloe, everywhere she went she had lots of friends. She was charming and polite, accepting and encouraging.
"She worked incredibly hard. She loved swimming, she was very focused on it and she wanted to go as far as she could. She was also bright academically, everything she did she gave 100 percent. We are very proud of her."
Chloe, a member of both Swim Trafford and Altrincham Swimming Club, had been at an awards ceremony on Saturday where she was presented with the outstanding achievement award.
She later went to a party at a friend's house.
Detective Inspector Debbie Oakes, from Greater Manchester Police, stressed there are no suspicious circumstances.
She said: "Chloe was an exceptionally bright girl with a huge future. Her family have suffered an unimaginable loss and our thoughts are with them at what is clearly a traumatic time for them."
Details have been passed to the coroner.
