OAKLAND, Calif. (KGO) -- Hundreds of protesters participated in what started as, and was intended to be, a peaceful march through the streets of downtown Oakland Saturday evening to show support for the ongoing protests continuing in Portland since George Floyd's death nearly two months ago.
The event began at 7:30 p.m. at Frank H. Ogawa Plaza at 14th Street and Broadway in Oakland, according to organizers which included the Wall of Moms Bay Area, Refuse Fascism Bay Area and Vigil for Democracy.
The Wall of Moms group encouraged participants to wear yellow and bring sunflowers. All must wear masks to prevent the spread of COVID-19.
"Reject secret federal police in our cities, and celebrate our right to gather peacefully and protest," the moms' group Facebook page says.
Crowds were seen marching through downtown Oakland.
The Oakland Police Department partially opened their Emergency Operations Center Saturday afternoon to monitor the protest, Officer Johanna Watson said. The Alameda County Sheriff will be standing by if mutual aid is requested.
Officials tweeted that some people within the hundreds of demonstrators vandalized the police station by breaking windows, spray painting and shooting fireworks.
Attendees made their way towards the area of 17th and Lakeside and began shouting racial slurs and breaking windows, officials tweeted.
Around 10:30 p.m., a small debris fire broke out at the Alameda County Superior Courthouse and police said it was caused by "agitators within the crowd of demonstrators." Crews contained the fire shortly after.
Shortly before midnight, Oakland police tweeted video of a person removing barricades placed in front of the police headquarters. Police say they asked crowds to disperse and deemed the situation an unlawful assembly.

Federal officers were sent by President Donald Trump to protect federal property in Portland, but their presence has escalated tensions and drawn several other groups to the protests.
Wall of Moms groups formed in recent weeks after Trump announced he was sending federal troops to Democratic-led cities.
In Seattle, thousands of protesters initially gathered peacefully near downtown on Saturday in a show of solidarity with fellow demonstrators in Portland.
Seattle police declared a riot following large demonstrations in the city's Capitol Hill neighborhood and deployed flash bangs and pepper spray to try to clear an area near where weeks earlier people had set up an "occupied protest zone" that stretched for several blocks.
Via Twitter, police said they had made some arrests Saturday and were "investigating a possible explosive damage'' to the walls of the city's East Precinct police station.
Authorities said rocks and bottles were thrown at officers. More than two dozen people were arrested.
