LOS ANGELES (CNS) — A 30-year-old Long Beach man was in custody Thursday in connection with a stabbing that occurred last month during dueling demonstrations in downtown Los Angeles over COVID-19 vaccine mandates.

Eric Cohen was arrested on suspicion of attempted murder Wednesday and booked into the Metropolitan Detention Center, according to the Los Angeles Police Department. His bail was set at $1 million.

During a Thursday morning TV appearance, Los Angeles Police Department Chief Michel Moore said video from the scene of the Aug. 14 protests outside Los Angeles City Hall also captured a second stabbing, but that victim has not yet come forward.

Vaccine supporters had gathered for a "No Safe Space For Fascists" rally at the intersection of First and Spring streets, followed one hour later by a "Choose Freedom March" against "medical tyranny."

At the peak of the rallies, about 500 anti-vaccination protesters were on City Hall's South Lawn and about 30 to 50 counter protesters were at First and Spring streets, according to police. The LAPD deployed 100 personnel to the event.

Video from the scene showed the anti-vaccination crowd yelling at the other side from across First Street, with the scene subsequently devolving into a melee.

Both sides could be seen exchanging punches and throwing objects at each other. The clash lasted about two minutes, Moore said.

The stabbing victim suffered a lacerated heart and punctured lung, but is expected to survive, Moore said.

"This anti-vax debate is manifesting itself in protests and demonstrations and violence in other parts of the country as well," Moore said during the appearance on television. "In Los Angeles, we're not going to stand for it. Our arrest last night demonstrates that we'll put whatever resources we need to identify those responsible for such violence and bring them to criminal justice system."
