One person was killed and nine injured, including children, in a roller coaster accident at the Grona Lund amusement park in the Swedish capital on Sunday, representatives of the park said, El.kz cites Reuters.
Eyewitnesses said the park's Jetline roller coaster had partly derailed during a ride, sending people crashing to the ground.
"Today is a day of mourning at Grona Lund, we've had a very serious accident in the roller coaster Jetline, where one person has died and nine people have been injured," Jan Eriksson, the park's chief executive, said in a press conference.
Ambulances, fire trucks and a helicopter were seen arriving shortly after the accident, and police launched an investigation.
Police said the nine injured people were being treated in hospital, and that three had severe injuries.
"Something like this should not happen at Grona Lund, and yet it happened", Eriksson said, adding that the 140-year-old park would be closed for at least a week to aid the police investigation.
The park spokesperson said 14 people were on the roller coaster when the front part partially derailed. It then stopped in the middle of the track with one carriage leaning out.
