LOS ANGELES — Litigation is piling up against organizers of the Fyre Festival that flamed out in a fiasco.

Angry participants had lashed out on social media with the hashtag #fyrefraud as the music festival fell apart on an island in the Bahamas in April — and fraud is the first claim in a $100 million class-action suit.

The suit amended earlier this month in federal court on behalf of a Los Angeles man said the events planned over two weekends were “nothing more than a get-rich-quick scam” akin to a Ponzi scheme that put the lives — and small fortunes — of thousands of participants in jeopardy.

“The festival’s lack of adequate food, water, shelter, and medical care created a dangerous and panicked situation among attendees — suddenly finding themselves stranded on a remote island without basic provisions — that was closer to ‘The Hunger Games’ or ‘Lord of the Flies’ than Coachella,” according to the suit filed by attorney Mark Geragos.

The lawsuit is one of several filed in the wake of the disaster that unfolded late last month when inadequate planning and facilities led performers to bow out and organizers to cancel the show.

In the amended complaint filed in U.S. District Court, Geragos said 300 people had contacted his offices after the initial suit was filed last month against organizers Billy McFarland, rapper Ja Rule, who was born Jeffrey Atkins, and Fyre Media Inc. Among dozens of defendants are deep-pocketed investors who provided seed money for the event.

Lawsuits filed in New York and Miami federal courts made similar claims after Geragos filed the Los Angeles case. Attorney Stacey Richman, who represents Ja Rule, said he wouldn’t participate in anything fraudulent.
