Nearly all signs of a weeklong encampment that took over the commencement stage at Pomona College were gone Monday, a day after protesters gathered outside the Shrine Auditorium in Los Angeles for the college’s relocated graduation ceremony.

Messages spray-painted in red — “We’ll be back” and “Free Palestine” — on the side of the Smith Campus Center were all that remained Monday morning of the pro-Palestinian encampment that took over Marston Quadrangle for six days.

The day before, protesters decamped and regrouped at the auditorium after the college changed commencement venues.

By late afternoon Sunday, about 100 protesters were outside the Shrine, chanting such slogans as “We will not stop, we will not rest” while banging on buckets and drums. Shoving matches broke out as guests made their way to the venue for the 6 p.m. ceremony.

Demonstrators clustered at the two corners along Royal Street, shouting and waving flags and posters. At Royal Street and Jefferson Boulevard, brief pushing matches took place between protesters, security guards, police and commencement guests around 5 p.m. as attendees tried to enter the auditorium.

One woman trying to enter the auditorium was overheard saying protesters came into contact with her husband and that she’d called police, but it wasn’t clear exactly what occurred. Officers were already on the premises, but apparently not in the immediate vicinity. The woman declined to comment as she and others waited at a side entrance of the auditorium in hopes the venue’s staff would let them in.

Tensions between law enforcement officials and protesters came to a head shortly after 6 p.m., when several dozen police officers, many wearing riot helmets and carrying batons, formed a line and advanced to keep protesters back. Using a loudspeaker, they told protesters to disperse.

After a tense standoff, protesters walked down West 32nd Street, away from the auditorium while police continued to hold the line as of about 7 p.m. Protesters had not returned to the auditorium as of 9 p.m., when commencement was winding down.

It is not clear how many demonstrators were Pomona College students or how many had joined from encampments at other schools.

Speakers with megaphones led the chants and unfurled red banners that demanded Pomona College divest from what they called genocide and apartheid. Some waved Palestinian flags. Behind them, commencement guests trickled into the venue.

Los Angeles police arrested one protester on suspicion of battery on an officer after an attempt to strike an officer, according to a department tweet. No other arrests were made as of about 8 p.m. and only a small group of protesters remained in the area, according to the tweet.

Pomona College officials on Friday apologized for the “inconvenience” associated with the changes to commencement.

“We are deeply grateful for our community’s patience in this extraordinary situation, and we look forward to honoring our graduates on Sunday,” the college said in the statement. “These changes were made to ensure that the Class of 2024 can graduate with their loved ones in attendance.”

On Sunday night, Pomona College spokesperson Patricia Zurita Vest emailed a statement that said: “We were able to honor close to 400 graduates this evening with their loved ones joining them in a packed Commencement ceremony at the historic Shrine Auditorium. We appreciate the patience of the graduates and families with the shift this year.”

At the commencement, one graduate said he was removed from the ceremony by security guards before walking across the stage.

Marcello Ursic, who wore a keffiyeh over his gown, said he took photos, was yelled at by security and called “an agitator.”

“I was standing inside, I looked around, took a photo — they didn’t want me taking a photo, I guess,” he said while sitting outside the auditorium.

Ursic said he was taken “into a back room.”

The three photos Ursic took appear to show a doorway leading from the building to the attached parking garage, Dean Avis Hinkson and another person speaking to security personnel, and a padlocked exit door.

Zurita Vest’s statement did not address why the student was ejected.

The pro-Palestinian encampment began May 6, about a month after an earlier encampment was dismantled by officials and police arrested 20 Pomona College students when they took over an administration building on campus.

Before they decamped Sunday, protest organizers said in a social media post Sunday they were “not returning to Pomona College today” and instead would focus their efforts on activities at the Shrine Auditorium. It was not clear if or when protesters would return.

College officials took note of the group’s message, however, and decided to take action.

“On Sunday, protest social media accounts announced the end of the encampment and the individuals involved left the quad on their own,” the college said in a statement Monday. “Our campus facilities team then began cleaning up the large amount of material left behind. We are grateful for the hard work of our facilities team.”
