"They were never able to occupy a building outside of City Hall," Jordan said Sunday. "We suspect they will try to go to the convention center again. They will get not get in"
Saturday's protests – the most turbulent since Oakland police forcefully dismantled an Occupy encampment in November – came just days after the group said it planned to use a vacant convention center building as a social center and political hub and threatened to try to shut down the Port of Oakland for a third time, occupy the airport and take over City Hall.
Quan, who faced heavy criticism for the police action last fall, on Saturday called on the Occupy movement to "stop using Oakland as its playground."
"People in the community and people in the Occupy movement have to stop making excuses for this behavior," Quan said.
On Sunday, Quan said she is tired of the protesters' repeated actions.
"I'm mostly frustrated because it appears that most of them constantly come from outside of Oakland," Quan said. "I think a lot of the young people who come to these demonstrations think they're being revolutionary when they're really hurting the people they claim that they are representing."
Saturday's events began late Saturday morning, when a group assembled outside City Hall and marched through the streets, disrupting traffic as they threatened to take over the vacant Henry Kaiser Convention Center.
The protesters then walked to the convention center, where some started tearing down perimeter fencing and "destroying construction equipment" shortly before 3 p.m., police said.
Police said they issued a dispersal order and used smoke and tear gas after some protesters pelted them with bottles, rocks, burning flares and other objects.
The number of demonstrators swelled as the day wore on, with afternoon estimates ranging from about 1,000 to 2,000 people.
