A fight among at least six students at Mountain View High School in El Monte on Friday escalated an hour after dismissal into a second brawl involving family members outside the campus, ending with a school resource officer forcing a woman to the ground and two people under arrest.
The initial fight broke out around 12:15 p.m. Friday and was broken up by campus staff, according to the El Monte Police Department, as reported by KTLA. A student was arrested in connection with that altercation and an alleged assault on a school staff member, then booked and released into the care of their parents, per the outlet's report.
Roughly an hour after school let out, family members of the students involved in the earlier fight squared off in front of the school in the 2900 block of Parkway Drive, according to the same account. A school resource officer already on scene tried to intervene and attempted to detain one of the involved parties, a female adult, but police said she struggled with the officer and refused to comply with orders.
Officer Forces Woman to Ground During Struggle
Police said the officer ultimately forced the woman to the ground in order to detain her, and additional El Monte police officers were called in to separate the fighting families. The woman was arrested and charged with obstruction, according to police, who described her as having resisted the officer's lawful action.
Investigators said no guns or other weapons were used during either fight, and police reported that no one involved suffered serious injuries. A portion of the incident was captured on video and has been shared on social media and other outlets, according to police, who said the investigation into both fights remains ongoing.
Legal Exposure for Both Arrests
The adult woman's obstruction arrest falls under California Penal Code Section 148(a)(1), which makes it a misdemeanor to willfully resist, delay, or obstruct a peace officer performing their duties, punishable by up to a year in county jail and fines up to $1,000, according to FindLaw. The statute does not require physical violence to apply — only intentional interference with an officer's lawful actions.

The statute does not require physical violence to apply — only intentional interference with an officer's lawful actions. The child arrested after the alleged assault on campus staff could face scrutiny under California Penal Code Section 243.6, which classifies battery against a school employee performing official duties as a misdemeanor carrying up to a year in county jail and a $2,000 fine, with the potential to escalate to a state prison sentence if the employee is injured, according to the Shouse Law Group. The statute specifically addresses battery against a school employee performing official duties.
Why an Officer Was Already on Campus
An officer was present during dismissal at Mountain View High. It is one of five comprehensive high schools within the district.
The district also relies on digital security tools including Verkada visitor badge tracking at entrances and public address horn speakers for emergency communications across its high school facilities, according to Verkada. Those systems are designed to manage who enters campus and to help staff respond quickly when incidents unfold.
A Familiar September Pattern Nationwide
The timing of Friday's altercation fits a pattern seen well beyond El Monte. An August 2025 FBI special report on school crime found that personal weapons — hands, fists, and feet — were the most common weapon type involved in campus criminal incidents nationwide from 2020 through 2024, with most criminal incidents occurring in September, according to the FBI. Federal survey data from the National Center for Education Statistics separately found that 61% of U.S. public schools reported at least one physical attack or fight without a weapon during the 2021–22 school year.
The Educator's School Safety Network's 2024–2025 annual report similarly found that while total school threats decreased nationwide, physical violent incidents in schools remained elevated compared to pre-pandemic baselines. California law already requires public schools to maintain and annually update Comprehensive School Safety Plans specifying crime prevention strategies and emergency response procedures, per the California Department of Education, though it remains unclear what specific triggered the initial fight at Mountain View High.
El Monte police said the investigation into both fights is ongoing and asked anyone with information to contact the department's watch commander at (626) 580-2109. Anonymous tipsters can also reach Crime Stoppers at (800) 222-8477.
