Police in Southern California say they are investigating a violent fight over the weekend. The altercation, partially captured on cellphone video and shared on social media, occurred Friday.

"They were throwing fireworks, they were bellicose," said a Marine who claims to have been beaten by the youths. "Our officers arrived at the scene and investigated the incident," the sheriff's office said. "The Orange County Sheriff's Office will continue to investigate the incident until all responsible persons are identified and prosecuted," it said.
