July Fourth chaos erupted over the weekend on the West Coast. More than 400 teens and young people were arrested during a massive teen takeover event in Newport Beach, California.
Police say the mob descended upon the Balboa Peninsula neighborhood on July 4, with videos shared on social media depicting the madness with crowds appearing to set off fireworks in the middle of roadways, block busy streets and cause damage to local businesses.
From Friday, July 3, through Sunday, July 5, police made 402 arrests, with the local fire department responding to 102 emergencies, including 10 fires; it is unclear if the fires and emergencies were related to the illegal takeover event.

"Social media posts drew a large influx of juveniles and young adults to the Newport Pier area within a matter of minutes. As the crowd quickly grew into the thousands, dangerous and unlawful behavior escalated, blocking roadways, preventing emergency access and putting families, visitors and first responders at risk."
