UPDATED: One Arrested as Protesters Line Murrieta Border Patrol Facility Entrance

At least one protester was arrested July 4 outside the Border Patrol station in Murrieta, as tensions rose among immigration protesters.

Three other people were arrested, including a woman who allegedly jumped on a police officer, according to ABC 7.

The protester was seen calmly walking toward a police squad car while demonstrations both opposing and supporting the federal government's immigration policies lined a rural road and shouted at each other.

The protester, Larry Spencer, 54, of Hemet, was arrested on a misdemeanor violation of disobeying a lawful order of a police officer. He was brought to the Murrieta police station, where he was cited and released, according to Murrieta police Capt. Dennis Vrooman.

Spencer allegedly refusal to stay behind a designated line for protesters. His arrest was the only one to occur during the tense standoff, according to Vrooman. The number of protesters appeared to have dwindled as the day progressed.

There was a report of one person being treated for heat exhaustion. There was another about additional arrests having occurred, but the information was not confirmed, according to KCAL9.

"It's a free speech issue, and I don't cede that too easily," Spencer told CBS2. "I am not going anywhere."

Police officers created a barrier with yellow police tape in between immigration protesters and supporters by midday.

The demonstrators were kept under the watchful eye of police and federal agents as the effort to keep 140 immigrants who were expected to arrive on a bus from entering the Border Patrol processing center continued throughout the day.

"The Border Patrol assisted us," the police captain said.

As a line of Murrieta police cars lined Madison Avenue near the processing center, officers told an angry phalanx of demonstrators through a bull horn to keep things peaceful during their wait for the bus.

Immigrant advocates faced off with anti-immigrant protesters while a group of Aztec dancers played drums in the background and performed.

The figure of a man made of tape sporting a white T-shirt saying "I love immigrants" was propped on the shoulders of one pro-immigrant protester while other demonstrators chanted slogans for undocumented immigrant to go back home.

One resident, Nevada Gutierrez, tweeted that she lives in a nearby community and reported that the "tension is palpable from here."

An immigrant advocate, Luis Nolasco, of San Bernardino, told City News Service that the gathering of more than 100 demonstrators was highlighted by chants and shouting.

"People need to remember that the ongoing immigration issue is also a "humanitarian one," Nolasco said.

"It's a refugee crisis," he added.

Both the mayor and city manager of Murrieta have said the Tuesday blockade of three buses by relocation opponents has given the city a "black eye," an image that does not reflect the "compassionate and caring" nature of the city.

"We have been challenged, and in some ways we fell down in the face of the challenge" presented by protesters who succeeded in blocking three buses from arriving at the Murrieta Border Patrol station, City Manager Rick Dudley wrote in an open letter posted Thursday night.

Since the protest, long sections of rural roadways near the Border Patrol station have been marked "no parking," and both sides of the issue have been given assembly areas. But law enforcement officials have said a repeat of Tuesday's blockade of the buses, presumably carrying women and children will not be allowed.

The gate to the Border Patrol station was protected by several dozen police Friday, as 140 women and children from Central America were rumored to be heading from San Diego to the Murrieta station. There, they were to be processed and in many cases, released to travel.

On Monday, Murrieta mayor Alan Long appeared on national television and encouraged residents to protest the use of the federal facility in Murrieta.

But Long told City News Service Friday that immigration reform needs to take place on the federal level, and not in the streets.

The unresolved issue over immigration must be "where we should focus our attention to," Long said.
