OAKLAND, Calif. (KGO) -- Hundreds of people took part in a protest Saturday night in Oakland that led to "several" arrests and damage to the Alameda County courthouse and police station. The march through downtown protesting racial injustice turned violent when demonstrators clashed with police and a fire was set at the courthouse.

Police say demonstrators set fire inside the Alameda County Courthouse in Oakland on Saturday night. SKY7, captured another fire set outside the building. The Oakland Fire Department put both fires out quickly.
Windows were broken at a police station and at a nearby apartment building. At Oakland Police headquarters, a group kicked down a baracade surrounding the police department.
"I saw a lot of intensity, people are very upset," said Vanessa Dove.
Dove is from the Bay Area Street Medic Alliance who joined hundreds on the street.
It began as a peaceful protest through downtown Oakland in support of Black Lives Matter and police reform and against Federal agents being deployed to Portland, Oregon to dispurse demonstrators.
"There were grandmas, and grandpas, veterans, who are sick of police oppression," said Dove.
Later, some demonstrators broke away from the larger group -- smashing windows and spray painting graffiti and pointing lasers at police officers.
Oakland Police declared it an unlawful assembly, tweeting: "We are asking agitators to stop throwing items and pointing lasers at officers at 7th and Broadway"
Mayor Libby Schaaf said in a statement:
"Vandalizing our downtown gives Donald Trump the images he wants and the justification he seeks to send Federal troops into American cities. We celebrate passionate protest but Oaklanders need to know that when they attend protests after dark, they may be providing cover for agitators who are more intent on stoking civil unrest than advancing racial justice."
This comes after the president suggested last week that he'd send federal agents in cities like Oakland, New York and Chicago in response to protests.
Oakland native Phillip Johnson is disappointed, he believes the actions of some distract from the Black Lives Matter movement.
"This is a bad image for Oakland, this isn't going to bring Floyd back, this is damage for the City of Oakland, period," said Johnson.
