SeaWorld's Electric Eel coaster has been closed since early June after a rider suffered a leg injury on the attraction, Cal/OSHA said.
The injury was reported to the state Division of Occupational Safety and Health, or Cal/OSHA, on June 9. Amusement parks and owners are required by law to report an injury or accident on a ride.
The state agency, which regulates public health and safety in workplaces as well as amusement park attractions and ski lifts, is investigating the Electric Eel incident.
