One person reportedly killed and many injured in Sweden rollercoaster incident

One person has died and nine have been hospitalised after an incident at a Swedish theme park where several people fell off a ride, local media has reported.

On its website, Stockholm theme park Gröna Lund said on Sunday that there had been a "serious accident".

Park officials told public broadcaster SVT that one of the carriages on the Jetline rollercoaster derailed and people fell to the ground at the Gröna Lund amusement park.

Stockholm Police said the incident involved both children and adults and three of those involved were seriously injured. The force is investigating the cause.

The park will be closed until further notice.

SVT reporter Jenny Lagerstedt, who was standing in line for another ride, said the carriage was at a high altitude.

“Suddenly I heard a metallic thud and then the rides started to shake,” she said. Rescuers had to remove other passengers who were stuck in other carriages on the roller coaster after the accident.
