In a major breakthrough, FBI Deputy Director Dan Bongino confirmed the arrest of a California man accused of launching concrete blocks at federal immigration officers during a volatile anti-ICE riot last month — an attack that left one agent injured and several government vehicles damaged.

The suspect, Elpidio Reyna, 39, of Compton, was captured Wednesday morning at the U.S.-Mexico border after weeks on the run. According to Fox 11, Reyna was arrested at the San Ysidro Port of Entry by FBI agents, with assistance from U.S. Customs and Border Protection.

Reyna was wanted in connection with a June 7 assault on federal law enforcement in Paramount, California, where a protest spiraled into chaos after Border Patrol agents established a staging area for immigration operations. According to the FBI, the crowd turned violent, hurling rocks, concrete blocks, and glass bottles at officers, prompting agents to deploy tear gas in self-defense.

Video footage aired by Fox shows the moment agents were forced to retreat under a hail of projectiles.

“You may remember Elpidio Reyna, a subject who allegedly threw rocks at federal officers during immigration operations in California June 7,” Bongino posted on his official FBI X account. “We got him. He was arrested today at the U.S.-Mexico border.”

“More to come,” Bongino warned. “Those who attack America’s police officers can run but they can’t hide.”

According to the U.S. Attorney for the Central District of California, Bill Essayli, Reyna now faces a felony charge of assault on a federal officer.

“Elpidio Reyna surrendered today at the U.S.-Mexico border to face a felony charge of assault on a federal officer for throwing rocks at passing law enforcement vehicles in Paramount on June 7,” Essayli confirmed on X.

“He was taken into custody by a U.S. Border Patrol officer who was inside one of the vehicles damaged in the attack — a brave law enforcement officer who could have been killed in last month’s dangerous and reckless attack.”

“To anyone who thinks they can attack federal officers and hide behind a mask or helmet, Reyna’s arrest today proves we can find and charge anyone who violates federal law,” Essayli added. “Don’t touch our officers.”

FBI agents had already identified Reyna shortly after the violent incident using social media clips and local news footage. But investigators learned he had fled to Mexico, where he remained in hiding for several weeks. His face was broadcast across Southern California and parts of Mexico, leading to his eventual capture by Mexican authorities in Sinaloa.

Following a negotiation process, Reyna voluntarily surrendered to the FBI at the border. He was transported to Los Angeles for an initial court appearance.

The June riot was one of several in the Los Angeles area that erupted in the wake of federal ICE operations targeting repeat offenders and criminal aliens. In response, President Donald J. Trump deployed 700 U.S. Marines and federalized over 4,000 National Guard troops to restore order, drawing fierce condemnation from California Governor Gavin Newsom and Los Angeles Mayor Karen Bass.

Newsom sued the Trump administration, claiming the troop deployment violated the Posse Comitatus Act, which limits the use of military forces in domestic law enforcement. A federal judge initially ruled in Newsom’s favor, but that order was overturned by an appeals court, which allowed federal authority over the Guard to stand.

Despite the political firestorm, federal officials insisted the response was measured and necessary to restore law and order amid dangerous attacks on law enforcement personnel.
