Gatecrashers attacked the latest mega-rave in Southern California, last weekend's 420 Festival in Orange County's Santiago Canyon, recalling images of last summer's embattled Electric Daisy Carnival at the L.A. Coliseum.

But the one-day event was otherwise safe and peaceful, authorities told the Weekly.

Orange County Sheriff's Department spokesman Jim Amormino told us a few of the gatecrashers were “ejected” and that only …

… one suspect was arrested — for allegedly breaking into a car.

Greg McKeown, spokesman for the Orange County Fire Authority, said there were only three medical-emergency responses, including one for a respiratory problem, one for a “psych” issue, and one for an injury. Those latter two victims were taken to hospitals, he said.

Not bad considering capacity was said to be 10,000.

Anti-drug activists called the party out for its clear drug references. Turns out it was pretty mellow after all.

Talent included LMFAO, Junior Sanchez, Adam F, Swedish Egil and DJ Reza.

In contrast, June's two-day Electric Daisy Carnival saw more than 200 medical emergencies, 60 mostly drug-related arrests and the subsequent death of a 15-year-old girl who had overdosed on ecstasy.

That party's problems led to a call for a ban on raves at the Coliseum and adjacent Sports Arena, both publicly-run venues. Rather than fight to stay, EDC's organizers moved the event to Las Vegas and expanded it to three days.
