Thirty-two people were hospitalized and 300 were arrested over the Labor Day weekend at the Nocturnal Wonderland dance festival attended by nearly 85,000 people in Devore.

More than a third of the arrests — 130 — were for drug-related offenses, and 37 of them were federal cases prompting arrests by the Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives, according to a breakdown by the San Bernardino County Sheriff’s Department breakdown.

Of the 32 people hospitalized, two were flown out from the San Manuel Amphitheater by helicopter. Only one of the 32 people remained hospitalized as of Friday, sheriff’s spokeswoman Cindy Bachman said.

“That is pretty amazing considering it is an event attended by thousands of people over a five-day period,” Bachman said in an email.

The condition of the hospitalized individual, whose age and gender were not disclosed, was said to be improving, county spokesman David Wert said Friday. That person’s hospitalization was not drug-related, sheriff’s officials said.

According to event promoter Insomniac Events, nearly 85,000 people attended Nocturnal Wonderland’s 20-year anniversary event, which began Thursday with overnight camping and concluded at 2 a.m. Monday, with most attendees cleared out by 3 p.m. Monday.

Wert said that county staff has not had an opportunity to evaluate the numbers from the event and determine whether a recommendation to the Board of Supervisors would be in order to ban the events.
