OAKLAND (CBS SF) -- Police declared an unlawful assembly Thursday night as hundreds of protesters gathered in downtown Oakland for a third night of demonstrations against the election of Donald Trump as President of the United States.
Around 9:30 p.m. police said protesters had moved onto Interstate 580 near Telegraph Avenue.
Then around 9:45 p.m. the California Highway Patrol said eastbound Highway 580 had been blocked by a group of roughly 100 people east of the I-980 interchange.
Two people were arrested on the highway after they broke through a fence, according to the CHP. Police said that tear gas was also deployed on Thursday.
An estimated 7,000 people protested on Wednesday night. Demonstrators grew violent as the evening wore on, with police using tear gas and flash bang grenades and protesters throwing rocks, bottles and fireworks.
Cat Brooks of the Anti Police Terror Project addressed the crowd, saying that it was the police who incited the violence.
Police said they used tear gas only after provoked.
"This is censorship at the hands of Libby Schaaf and OPD," Brooks said, but called for discipline on tonight's march.
"We do not accept or acknowledge the fascist regime of Donald Trump or Libby Schaaf nor do we recognize the authority of her gestapo, otherwise known as OPD."
