Huntington Beach is cleaning up Monday morning after a fight broke out following the U.S. Open of Surfing, leading to a two-hour confrontation between police and unruly beachgoers.
Eight people were arrested and several officers were injured Sunday night. Police in riot gear used tear gas and nonlethal rounds to disperse the crowd, which tipped over portable toilets and smashed storefront windows.
Huntington Beach Police Lt. John Domingo said city signs and vehicles were also damaged.
The U.S. Open of Surfing draws thousands of people to Huntington Beach. Hundreds of people were still in the area when the unrest began, with many of them posting photos and videos to social media.
[For the record, 11:50 a.m. on July 29: An earlier version of this post included an Instagram from @dj_alex_goodrow, who tagged his photo #riot #huntingtonbeach. However, the photo is from a 2011 riot in Vancouver.]
