LOS ANGELES _ More than 400 people were arrested and five people hospitalized during a three-day Labor Day weekend electronic music festival in San Bernardino County.
Attendance at the Nocturnal Wonderland rave topped 67,195 over three days.
On Friday, the first night of the rave, 111 people were arrested during security screening at the entrance to the San Manuel Amphitheater in Devore, according to the San Bernardino County Sheriff's Department. One sheriff's deputy sustained minor injuries during an arrest Friday evening. He was hospitalized and later released.
Six people were arrested for being younger than 18, the legal age for admission. Another person was arrested on suspicion of driving under the influence and crashing into a San Bernardino County sheriff's deputy and his motorcycle, authorities said. The deputy was not injured.
On Saturday, 141 people were arrested on suspicion of offenses including drug possession, drug sales, assault and battery, and being under the influence of drugs or alcohol. One person was arrested for indecent exposure, sheriff's officials said.
On Sunday and early Monday, when the festival ended, 176 people were arrested, mostly for being under the influence of drugs or alcohol. Two people were taken to hospitals.
One person was assaulted and suffered traumatic injuries to his face.
The sprawling festival _ with performers on five stages and headliners including Above & Beyond, DJ Snake and Bassnectar _ was put on by Insomniac Events, a Live Nation subsidiary, which leases the amphitheater from the county.
Similar music festivals have brought a rash of deaths of young concertgoers, often from drug overdoses.
Ecstasy and similar club drugs are seen by some as part of the festival experience and consumed for their stimulating and euphoric effects. Three people died in July after attending the Hard Summer rave near Fontana.
Since 2006, three people have died of overdoses at Nocturnal Wonderland festivals. The most recent occurred in 2013, when a 22-year-old man died of an Ecstasy and methamphetamine overdose.
Several physicians have said raves threaten public health and overwhelm hospitals and emergency rooms with cases of seizure, coma or death from illicit drugs.
Noting that there had been complaints, the Sheriff's Department said a sound engineer and a deputy visited the area and determined that the volume was under the threshold of the county's noise ordinance.
