A brute suspected of savagely beating a woman unconscious during a sold-out concert at the Rose Bowl this week has been arrested.

Julio Cesar Lopez Zavala was apprehended at his residence in Hawthorne, Calif. on Thursday, following a brutal incident at a Rüfüs Du Sol concert which gained widespread attention online, Pasadena Police informed KTLA.

Zavala was in attendance for the Australian EDM group’s concert on Aug. 16, when a drink was allegedly spilled on him.

The 23-year-old initially left the scene but returned approximately 30 minutes later, shouting and issuing violent threats towards victim Shelby Elston and her fiancé, according to Elston’s account on Facebook.

Elston, who hails from Phoenix, Ariz., attempted to defuse the situation by apologizing and placing herself between the two men, only to become the target of the attack.

“This man PUNCHED ME IN THE FACE! I was completely knocked out and there was blood pouring from my face,” Elston wrote in the social media post, asking for help identifying her attacker.

Elston claimed Zavala pushed her into the bleachers and repeatedly pummeled her, even after she had been knocked out cold, according to video captured by a witness.

Bystanders attempted to stop the onslaught by pulling Zavala’s pants down and exposing his butt as Elston’s fiancé shielded her, taking multiple punches to the back.

Elston was knocked unconscious and awoke minutes after the attack inside a medical tent at the famed venue.

Zavala allegedly fled the stadium and was on the run until his capture on Thursday.

Police credited the viral video and tips from other fans for helping to identify Zavala as the suspect, KTLA reported.

Fellow concert-goers filed complaints against the Rose Bowl and the band, saying they felt unsafe inside the venue.

“I’ve never seen any venue that has allowed the people to stand there in the walkways. It’s a hazard,” Christine Molina, who was in attendance with her daughter, told KTLA. “There were multiple security vendors working the venue. It wasn’t just one vendor, it was multiples, and the left hand didn’t know what the right hand was doing.” 

Molina says she was afraid of being crushed by the tightly compacted crowd and observed people openly using drugs inside the venue.

Elston, who was left with several bruises and soreness, has returned home to Arizona and expects to make a full recovery, she told the outlet.

Formal charges against Zavala are pending a review by the Los Angeles County District Attorney’s Office, the outlet reported, citing police.
