Police officers responded to reports of "unruly guests primarily juveniles" in the park and parking lot, the Mason Police Department confirmed to FOX News Monday. No arrests were made.

Ryan Smith, a resident of Milford, Ohio attended the amusement park Saturday with his family and told USA Today the park was crowded with large groups of older teens acting in an aggressive manner. "There were a lot of F-bombs. It felt rough," he told USA Today, adding that he believed the park was understaffed.

"The safety of our guests and associates is always our top priority," a statement from Kings Island sent to USA Today Sunday said. "On Saturday, the decision was made to close the park 30 minutes early due to unruly behavior and altercations involving a number of teenagers. This behavior did not align with our park’s values, and was not the experience we want any guest to have while visiting Kings Island."
