A rollercoaster partially derailed in Sweden, resulting in one fatality and four injuries.
Before the tragedy, witnesses said they heard a “metallic thud” and noticed the Jetline ride’s support beams beginning to tremble at Stockholm’s Grona Lund park.
One of the rollercoaster cars was observed leaving the tracks at a ‘high height’ before crashing to the earth.
The attraction, which is used by a million visitors each year, reaches a maximum speed of 56mph and a top altitude of 30 metres.
It’s known among rollercoaster buffs worldwide for having a rare curved lift hill, though it’s not clear where exactly the carriage derailed.
Jenny Lagerstedt, a journalist with Swedish broadcaster SVT who happened to be at the park with her family, said: ‘My husband saw a roller coaster car with people in it falling to the ground
‘My husband, who was sitting outside, saw how a carriage came loose and fell from a great height, and that there were people in it.’
The park was evacuated while paramedics, an air ambulance and fire engines descended on the scene.
Grona Lund’s communications chief, Annika Troselius, said: ‘It is incredibly tragic and shocking. Unfortunately, we have received the news that one person has died and that several others are injured.
‘This must not happen and it should not happen. We are all very taken and shocked and are currently focusing on taking care of all those affected and our staff.’
Local police said they have launched an investigation into the accident.
