At least 30 people were rushed to hospitals from raves held at fairgrounds in Pomona and San Bernardino during the Halloween weekend, authorities said this week.

Ambulances took 26 people to hospitals from the Escape: Psycho Circus rave at the National Orange Show Events Center fairgrounds in San Bernardino on Friday and Saturday; and four more were taken from the Hard Day of the Dead at the Los Angeles County fairgrounds in Pomona, authorities said.

“Most were combative,” said Tom Lynch, the EMS administrator for the Inland Counties Emergency Medical Agency, of the 26 patients taken to hospitals from the citrus fairgrounds in San Bernardino. Many were brought in because of drug overdoses or alcohol intoxication, Lynch said.

Of the four people taken by ambulance to hospitals from the Hard festival, two are suspected to be drug-related, said Cathy Chidester of the Los Angeles County Emergency Medical Services Agency.
