We are helping the riders out now, the first ones are down on the ground, says Clara Rosendahl, communications manager at Liseberg, to Aftonbladet.
The roller coaster, which begins with a steep climb followed by a long drop straight down, got stuck on its way up the first hill. It stopped at 4:30 p.m. on Sunday.
It's because a safety device has been activated, says Rosendahl.
