What happened at Cal Poly Pomona?
According to SGV CityWatch, a suspect was arrested on Oct. 22, 2026 and booked on suspicion of felony vandalism after a series of hateful graffiti incidents at California State Polytechnic University, Pomona. The first reported case dated back to Sept. 17. The vandalism was found in the University Library and two other buildings, mostly in restrooms and stairwells, and included a swastika painted on a library window.
University President Vanya Quiñones addressed the campus in a letter, and a university spokesperson declined to name the suspect or say whether the suspect was a student, citing the ongoing investigation. University Police said the suspect was identified through a collaborative effort. An arrest is not a conviction, and the suspect is presumed innocent.
Why do vandals target certain parts of a property?
Vandals target places where they expect to be alone for a few minutes. Restrooms, stairwells, back walls, alleys, loading docks and dark parking areas give them time and cover. The Cal Poly Pomona case followed that pattern, with most of the graffiti found in restrooms and stairwells rather than busy open areas.
On commercial and residential properties, the most common targets include:
Rear and side walls facing alleys or empty lots.
Trash enclosures, utility boxes and fences.
Stairwells and restrooms in office buildings and shopping centers.
Vacant units and buildings under construction.
Signs and monument walls near the street.
How do you prevent graffiti and vandalism on commercial property?
The most effective graffiti prevention combines fast removal with better visibility. Remove tags quickly so vandals do not get the attention they want, light the areas where they work and add regular patrol checks after hours. Cameras and clear signs help, but they work best when someone actually responds to what they show.
A practical prevention plan:
Remove it fast. Many cities recommend removing graffiti as soon as possible, often within a day or two, because quick removal discourages repeat tagging.
Light it up. Add bright, motion-activated lighting on back walls, alleys and trash enclosures.
Cut hiding spots. Trim landscaping and remove clutter near walls and entrances.
Use protective coatings. Anti-graffiti coatings make walls easier to clean.
Add cameras where vandals work. Point cameras at high-risk walls, stairwells and entrances, and check that they record at night.
Schedule patrol checks. Random after-hours patrols make it harder for vandals to predict when the property is empty.
Should you report graffiti to police before removing it?
Yes. Photograph the graffiti, note the date, time and location, and report it to your local police department before cleaning it. Under California Penal Code section 594, vandalism, including graffiti, is a crime, and the amount of damage can affect how it is charged. Police often link cases through photos of repeated tags.
Hate-motivated graffiti, like the messages found at Cal Poly Pomona, should always be reported to police right away. Keep the photos and any camera footage in case investigators ask for them.
How can security patrols help stop repeat vandalism?
Security patrols help by changing the odds for vandals. A marked patrol vehicle and an officer on foot make a property feel watched, and patrol reports show owners when and where problems happen. Over time, that record helps managers move lighting, cameras and patrol checks to the spots that need them most.
During each visit, a patrol officer can:
Walk back walls, stairwells, restrooms and trash areas.
Photograph any new graffiti or damage and add it to the patrol report.
Ask loiterers to leave and call police when needed.
Check doors, gates and lights and report anything broken.
Our vehicle patrol service is built for this kind of after-hours coverage, and our vacant property and fire watch guide covers sites that sit empty. Pomona property owners can learn more on our Pomona security services page.
