A popular roller coaster in California has been shut down following reports that dozens of riders have suffered brain injuries. The closures came after two women required emergency brain surgery following their rides on the attraction. One of the women, a 25-year-old, is currently unable to speak or breathe independently. The extent of injuries among other riders is still being assessed, though reports indicate a significant number have been affected. Authorities are investigating the cause of the incidents and the safety protocols of the ride. The roller coaster’s operator has not yet released an official statement regarding the situation or potential compensation for those injured. Further updates will be provided as the investigation unfolds in California.
