Five juvenile suspects were arrested in connection with the assault on three U.S. Marines carried out by a mob of teenagers on a beach in San Clemente, California, over Memorial Day weekend, San Clemente Mayor Chris Duncan confirmed to Fox News Digital on Tuesday.

The suspects were charged with felony assault with a deadly weapon and remain in custody, Duncan said. San Clemente’s mayor said investigators have identified at least four more juveniles involved who may be charged with misdemeanor assault and battery.

Duncan described the investigation into Friday night's incident as "very efficient and effective." He said investigators do not anticipate any additional arrests, but said that could change.

Orange County Sheriff's Department Sgt. Mike Woodroof said on Fox News' "The Story" that anyone, regardless of age, who "kicks another human being in the head to cause damage, internal injury to that magnitude will be arrested for a felony assault deadly weapon."

A video posted on the social media platform Nextdoor shows one person throwing a punch at one of the alleged victims from behind before a large fight breaks out. The injured victim lunges at his attacker. The group of teenagers and young adults was then seen kicking the victims.

Two victims were filmed lying on the ground in the fetal position and covering their heads as the mob kicked and punched them. A couple of bystanders intervened in the beating, with one woman standing between the victims and the attackers as she outstretched her arms and yelled, "Stop!"

The confrontation allegedly began when the Marines told the teenagers to stop lighting fireworks on the beach, according to KCAL.

In a press release, the sheriff's department said deputies responded to the San Clemente Pier at around 10 p.m. Friday night after being notified that a large group of juveniles had assaulted Marines.

Deputies arrived to find two injured Marines and rendered medical aid. The Marines declined transportation to the hospital.

U.S. Border Patrol Chief Raul Ortiz told his colleagues Tuesday that he has decided to retire, FOX News has confirmed.

Ortiz, who manages roughly 20,000 Border Patrol agents as the law enforcement arm of U.S. Customs and Border Protection, informed his colleagues in a note Tuesday that he would be retiring effective Friday, June 30.

He also said in the note that serving as Border Patrol chief, a post he held since he was appointed in August 2021, has "been one of the greatest honors and privileges."

"I leave at ease, knowing we have a tremendous uniformed and professional workforce, strong relationships with our union partners, and outstanding leaders who will continue to tirelessly advocate for you each day," Ortiz said in the note.

Ortiz navigated the Border Patrol through the COVID-19 pandemic and Title 42 emergency health restrictions. He has also been vocal about the Border Patrol’s struggle to maintain operational control of the United States-Mexico border.

During a House Homeland Security Committee hearing in March, Chairman Mark Green, R-Tenn., asked him: "Does DHS have operational control of our entire border?"

"No, sir," Ortiz replied.

It's not immediately clear who will replace him.

CBP Acting Commissioner Troy A. Miller released a statement confirming the retirement.

"Chief Ortiz is a true leader. I have benefited greatly from his partnership, expertise, wise counsel, and friendship over the years," Miller said. "Every single day, he champions the men and women of the Border Patrol and has worked tirelessly to ensure that they have the tools, resources, and support they need to do their jobs."

"He has numerous accolades and awards from his tenure in the Border Patrol, but the highest compliment we can bestow on him is that he is a great agent," he added. "I want to congratulate Chief Ortiz on his retirement after more than three decades of service to our country. I look forward to seeing him out on the water, fishing from his boat, as he enters this next and well-deserved chapter."

The U.S. Customs and Border Protection operates within the Department of Homeland Security and is charged with protecting the country’s international borders, including thousands of miles stretching between the U.S. with Mexico and Canada.

On Tuesday, Homeland Security Secretary Alejandro Mayorkas praised Ortiz and applauded his decision to remain as Border Patrol chief through previous contemplations of retirement.

"Selecting him to lead the Border Patrol was among the most important decisions I have made," Mayorkas said. "Chief Ortiz agreed to postpone his retirement several times since and the Border Patrol, the Department, and our country have been all the better for it."

Ortiz first joined the Border Patrol in the 1990s and has been an agent for 32 years.
