Riots Break Out at 'Electric Daisy' Film World Premiere

The world premiere of Electric Daisy Carnival Experience saw police calming down an unruly mob outside Grauman's Chinese Theatre on Wednesday night.

Los Angeles' KTLA-TV reported that DJ Kaskade had called for a "block party" outside Grauman's Chinese Theatre.

"Today@6pm in Hollywood @Mann's Chinese Theatre. ME+BIG SPEAKERS+MUSIC=BLOCK PARTY!!! RT!" he tweeted.

Thousands of people reportedly showed up to attend the party.

The LAPD was forced to shut down Hollywood Boulevard between Highland and Orange avenues, causing a massive traffic jam on Highland, Hollywood and the 101 freeway, Hollywood reporter stated.

In spite of Police orders to evacuate the area, many refused to do so. There were fights, people throwing bottles and setting fire to a cop car.

Police fired riot beanbags at the crowd, KTLA reported.

Erika Raney, communications director of Insomniac, which puts on the Electric Daisy event, said in a statement: "We are disappointed that a small group of people would try to mar a private documentary screening ofElectric Daisy Carnival Experience, and we are thankful that the LAPD were able to quickly restore order."

Kaskade's later Twitter update asking people to calm down said, "EVERYONE NEEDS TO GO HOME NOW! I DON'T WANT THIS TO REFLECT BADLY ON EDM OR WHAT WE ARE ABOUT. BE RESPECTFUL AND CHILL OUT!!!"

Electric Daisy Concert Experience, from director Kevin Kerslake, was shot at a private event Monday at the Music Box Theater in Hollywood, with plans to release it on 250 screens across the U.S. next week. It includes performances from David Guetta, Deadmau5 and Moby.
