A devastating incident occurred at Stockholm's Grona Lund park, where a rollercoaster accident claimed the life of one person and left at least nine others injured. Witnesses reported that the Jetline rollercoaster partially derailed, causing the horrifying incident. The ride, which reaches heights of 30m (90ft) and speeds of 90km/h (55mph), suffered a catastrophic failure.

Following the accident, the park was swiftly evacuated, and authorities, including the police and emergency services, rushed to the scene. Jan Eriksson, the park's chief executive, declared a "day of mourning" in response to the tragic event.

Out of the nine injured individuals, three are reported to be in critical condition and are currently receiving treatment at a nearby hospital.

The incident occurred shortly after 11:30 local time in Sweden (9:30 GMT). The rollercoaster had fourteen people on board when the front part of the ride detached from the vehicle, leaving it stranded in the middle of the track and causing passengers to be thrown to the ground.

Jenny Lagerstedt, who was at the park with her family, recounted the terrifying moment. She heard a metallic sound and witnessed the track shaking. Her husband saw a rollercoaster car, with people inside, plummet to the ground. Lagerstedt's children were understandably frightened by the ordeal.

Expressing his disbelief,  Eriksson stated, "Something like this should not happen at GronaLund, and yet it happened." As a result, the 140-year-old amusement park will remain closed for a week to allow the police to conduct a thorough investigation into the incident.

Grona Lund has taken immediate action to address the situation. Customers who had already purchased tickets for the affected period will receive full refunds. Annika Troselius, a spokesperson for Grona Lund, emphasized their commitment to thoroughly investigate the incident, stating, "It is important for us to do everything we can to get to the bottom of this."

Parisa Liljestrand, Sweden's culture minister, expressed her disbelief and extended her condolences upon learning about the tragic accident. The news has left many in shock and struggling to comprehend the gravity of the situation.
