Norwegian swimming champion Alexander Dale Oen has died in the US, aged 26, Norway's swimming federation says.
He was found collapsed in a shower late on Monday after training in Flagstaff, Arizona, Norwegian media say. Officials said he had suffered a cardiac arrest.
Dale Oen won gold in the 100m breaststroke at the World Championships in Shanghai in July 2011.
His triumph came just days after the attack in Norway by Anders Behring Breivik which killed 77 people.
