VALENCIA, Calif. — State safety regulators have launched an urgent investigation into a high-speed roller coaster at a California Six Flags park following reports linking the attraction to potential rider head injuries.

Park officials confirmed they are cooperating fully with state inspectors while reviewing maintenance logs and ride dynamics. The affected attraction has been temporarily closed to guests pending comprehensive structural assessments.

Consumer safety advocates have urged stringent oversight to guarantee rider protection before the coaster is cleared to resume operations.
