More than 400 people were arrested and at least five people were sent to the hospital during a three-day Labor Day weekend electronic music festival in Southern California.

The Los Angeles Times reported Monday that nearly 70,000 people attended the Nocturnal Wonderland festival in three days at the San Manuel Amphitheater in Devore.

The San Bernardino County Sheriff’s Department said that 111 people were arrested Friday during security screening at the entrance to the amphitheater. Police said 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. In the final two days, police arrested 176 additional people for being under the influence of drugs and alcohol.

One sheriff’s deputy was injured Friday night and was hospitalized with minor injuries. He was later released. Another deputy was involved in an accident Sunday when a person smashed into his police motorcycle, according to the Los Angeles Times. The deputy was uninjured and the person was arrested on suspicion of driving under the influence.

Electronic music festivals have been notoriously tied to drug overdoses of young adults. Some see ecstasy and club drugs as part of the experience. The LA Times noted that three people died in July during the Hard Summer festival in Fontana.

The most recent death at the Nocturnal Wonderland festival occurred in 2013 when a 22-year-old died after overdosing on ecstasy and meth.
