149 arrested at Huntington Beach birthday party that drew thousands, police say

At least 149 people were arrested in Huntington Beach after a birthday party invitation went viral on social media and drew "unruly crowds," according to police.

At least 149 people were arrested in Southern California's Huntington Beach over the weekend after a birthday party invitation went viral on social media and drew "unruly crowds," according to police. The Huntington Beach Police Department said it began making preparations for the "highly publicized event" earlier in the week after it became aware of a video posted on TikTok inviting people to the city's beach on Saturday evening for a large party, dubbed "Adrian's Kickback." A namesake hashtag has since been viewed more than 265 million times on the social media platform. The initial crowd that gathered at the beach that evening exploded to more than 2,500 people who descended on the downtown area and threw "bottles, rocks, fireworks and other items at officers," police said. Multiple businesses, numerous police vehicles and a lifeguard tower were also damaged from vandalism. However, no significant injuries were reported, according to police. Aerial footage of the scene shows throngs of people flooding the streets and blocking traffic near the pier in downtown Huntington Beach, about 35 miles south of Los Angeles.
