During an anti-Trump protest outside Los Angeles City Hall, a teenage boy was stabbed and left in critical condition after several fights broke out on a Friday afternoon.

The 17-year-old was among a large group of people in Downtown LA protesting against President Donald Trump’s immigration and deportation laws.

The protest collapsed into chaos and violence just after 1:30 p.m. when the fights broke out, the Los Angeles Police Department said.

Police responded to the area of 200 North Spring Street after getting calls for the stabbing.

The incident occurred when the unidentified teen found himself in the midst of a large crowd at a park near the city hall. He was seen shirtless and covered in blood, as captured in footage by KTLA.

The alleged victim dropped to the ground as several others rendered aid to him.

One witness claimed the stabbing was unexpected and the suspect wasn’t a protester.

According to a protester named Will, who witnessed the event, “I came to the protest, and there was a guy that came up who wasn’t even a part of the protest, and just shanked a dude.”

As the teen was on the ground, protesters continued to wave around multiple, non-American flags, including the Mexican and Argentinian flags.

Paramedics rushed the teen to a local hospital in critical condition, officials added.

The accused stabber was described as a “male Hispanic juvenile.”

Officials did not announce any arrests or charges in the violent stabbing.

The Post has reached out to the LAPD.

Before the stabbing, another crowd got into a melee where several protesters exchanged punches in the middle of the street before others broke them apart, feet away from city hall.

Several protesters were detained by police, the Los Angeles Times reported.

The violent demonstration marked the sixth day protesters took to the streets around the liberal city to protest Trump’s orders to strengthen immigration policy in the country including high schools students that walked out of class to join the rallies, according to the outlet.

Police did not reveal if the wounded teen was a student.

Officials dispersed the crowd around 1:50 p.m. with streets around the area blocked off for the investigation.

Protest organizers told the rally-goers to leave and go home so they can “regroup” and continue the protest a later day.

On Friday, a female activist was arrested in Bakersfield for replacing the American Flag with a Mexican one on a flagpole.

Crystal Aguilar, 24, was arrested for the stunt at Hart Park where she threw the American Flag into mud.

“You’re not going to tell me what to do, this is Mexican land, motherf—ker!” Aguilar screamed as three park rangers approached her, footage from the Kern County Sheriff’s Office captured.
