One person has reportedly been killed and several injured in a rollercoaster accident in Stockholm.
Witnesses told public broadcaster SVT that the ride at Grona Lund park had partly derailed.
Police confirmed several people had been injured.
“We are emptying the park and we’ve started our investigation,” a police spokesperson said.
A black banner on the park’s website said: “A serious accident has taken place on the Jetline. We are working with the rescue services. The park is closed for now.”
Cornelia, who had just been on the ride with her son, told Sweden’s TV4 that people started running.
“There was a lot of screaming. No one knew what was going on,” she said.

Sweden’s Expessen quoted a police officer as saying several people had fallen off the ride and were found on the floor, while several more were left stuck.
A witness queuing nearby also told the site they heard a sound and saw the rollercoaster’s wheels starting to come off.
The Jetline reaches 56mph (90kmh) and 30m (98ft) high, carries more than a million people per year, and costs 90 kronor to ride (£6.60).
