Swedish station SVT's correspondent reported that a rollercoaster derailment at a Swedish theme park left one person dead and seven injured. 

Police reported that the Stockhold theme park, Grona Lund, had a carriage of a Jetline rollercoaster break apart from the rail and collapse. The ride in question was launched in 1988 and travels around 90 kph. 
 
Grona Lund spokeswoman Cecilia Bjorling, the park's spokesperson told AFP that one person "unfortunately died," while Stockholm police confirmed seven of the injured were admitted to the hospital.  
 
Hakan Eriksson of the Swedish capital's emergency services reported that they received the call and after that, the park was evacuated so emergency services could go to the scene. 

Jenny Lagerstedt, a correspondent for SVT recalled that she "suddenly heard a metallic thud and then the rides started to shake,"  adding that her husband saw a car detach from the ride and plunge.

Parisa Liljestrand, the Culture Minister told TT news "I recently visited the park with my family and I can't even imagine how it must feel when the most beautiful day suddenly turns into a nightmare."
