Editor's Note: An earlier version of this article stated that Gutierrez was the organizer of Sunday's protest. However, Gutierrez hosted a separate Martin Luther King Jr. Day event on Monday during which City Council Member Nolan Sullivan was in attendance.

California's Vacaville Police Department was vandalized early Sunday night as an initially peaceful rally of almost 50 people in Andrews Park devolved into chaos. 

Video cameras outside of the station captured black-clad demonstrators holding "f**k the police," "Black Lives Matter," and "ACAB" signs as they approached the doors.

The vandals broke a glass door at the station and spray-painted graffiti including "profane and threatening" messages about the police, according to a post on the department's Facebook page. 

The page also noted that there had been reports of individuals breaking out the windows of cars with people inside. No one was reported injured.

"Later at Andrews Park, police found an abandoned cart with two machetes in it. A vehicle associated with the protestors, and with helmets found inside, was impounded," an additional post on the Facebook page noted.

The group also smashed windows at the nearby City Hall, doing what Vacaville Police Chief John Carli told KTXL, the Fox affiliate in Sacramento on Monday, was tantamount to at least $30,000 in damages. 

However, they did not enter either City Hall or the Vacaville Police Department.

Authorities told KTVU, the Fox-owned TV station in Oakland, that graffiti on and around the department matched that on signs on the downtown bridge.

No one has been arrested in connection with the incident, despite the significant destruction, though investigators are reviewing video footage.

Carli told reporters that the department is asking for the community's assistance in finding those responsible.

"Vacaville respects peaceful protests but what happened Sunday night was unacceptable," he wrote in a statement. "This does not reflect who we are as a community."

Aisha Gutierrez, who organized a separate and unrelated event on Monday, told KTXL the day was meant to bring people together and commemorate the values of American civil rights hero Martin Luther King Jr.

"This is the time I felt that we need to give a different image of gatherings, this isn’t a protest, this isn’t a rally but it’s a celebration of love to honor Dr. Martin Luther King," Gutierrez said. "Violence, none of that should ever be accepted, never be tolerated. The images we saw of the destruction last night were horrible and I just hope that this is giving the community that different image of positivity and peace and love."

In a post on her Facebook page, Gutierrez wrote that she was "saddened by the images of [their] Downtown."

"That should never be accepted or [tolerated]!! I truly believe there are more people in this City who believe in the spirit of Community, Peace, Unity & Family," she said.

Vacaville City Council Member Nolan Sullivan echoed Gutierrez's sentiment.

"Today’s display of courage and love was such an amazing counter to the lawlessness, violence and hate we have seen in our country, our state and sadly, Vacaville," he wrote in his own post. "Violence, hatred and chaos cannot be accepted. The assault on our downtown, police department and city hall last night cannot be tolerated, the violent attack on protestors two weeks ago cannot be tolerated. The events we all witnessed last week at our nation’s capital cannot be tolerated."

"We collectively need to turn down the heat and let some of the steam out of the pot. The community and the nation is at a boiling point and we all have a part in condemning violence, any violence and encouraging dialogue and hard conversation," he said. "We are better than this, we are more alike than we are different and again, Vacaville we have to do better."

Vacaville police's Lt. Chris Polen told Fox News the perpetrators were wearing masks, goggles, helmets, and carrying what looked to be sticks as they marched through the city -- a marked change from weeks past. He added that the department was getting "mixed messages" as to who might have been involved.

"Over the past several months, we've been seeing a slight change in behavior...It was kind of more of -- just argumentative with police [and] not wanting to follow instructions...but we didn't see a lot of vandalism," he said. "Hardly at all, actually. So, we didn't see vandalism occurring whether it was spray paint or broken windows. We didn't see any of that for a period of six months. But, this changed everything for us."

However, while the department has begun a criminal investigation, its focus is also on managing and mitigating potential future risks like Wednesday's inauguration.

"There's additional information that there might be protests tomorrow in Vacaville," Polen noted. "So, we've put up temporary fencing around the city hall campus and the police department. We're ramping up additional staffing to prepare for any violent protests."

"Obviously, peaceful protests are fine. We don't have a problem with that and we will support those measures and give you the freedom to do so. But, when it turns violent, we have a different course of action that we plan to make any and all arrests to prevent violence from occurring in our city," he said. 

Polen told Fox News he had seen a "significant change" in how people viewed policing and the department, noting that his colleagues have been working tirelessly to "try to give people the freedoms that they desire, [and] give them the peace that they want."

"So, our staff is tired. They're trying to endure the demands of society -- that's being placed on them," he said. "But, I will say that because we have a group of professionals that work in our organization, this law enforcement agency is something to be extremely proud of."

"We want to protect our culture. We want to protect our community," he concluded. "And, sometimes, we're losing that culture and that community by people who don't care about what Vacaville stands for."

The department asks that anyone with additional information that might help their investigation contact Detective Erik Watts at 707-449-5228.
