It was not the first time that an accident occurred in Cobra, which is a kind of roller coaster with hanging carriages.
In 2008, four people were injured when the attraction was new.
It was then shut down for several months.
The decision to close the ride comes from the amusement park's board, the amusement park announces in a press release.
The entire amusement park will also be closed for the next few days.
The accident is still being investigated by the police.
