Other protests have broken out in the San Diego, San Fransisco and San Jose areas, according to reports.
People could be heard chanting “Whose streets? Our streets” and “Not Our President”, according to Twitter users at the scene.

Anti-racist protesters are to stage a demonstration outside the US Embassy in London following the shock election victory.
Activists accused the President-elect of having a long history of “racist outbursts” as well as his promise to build a wall between the US and Mexico.
Sabby Dhalu, co-convener of the Stand up to Racism group, said: “Donald Trump used the oldest trick in the book – he stirred up fear and racism in the context of a stagnant economy and the resulting fall in living standards – to mobilise a vote for him.
“The danger now is racists across the globe feel emboldened by Donald Trump’s victory and racism and sexism become normalised through the most powerful figure in the world.
“We call on anti-racists and all progressives to join us tonight outside the US Embassy.”

Taking to the stage with his family, including wife Melania, Mr Trump promised a plan to double economic growth and invest in world-class infrastructure.
“Working together, we will begin the urgent task of rebuilding our nation and renewing the American dream.”
It would be a “beautiful thing”, he said.
The election of the outspoken businessman and TV personality, who has never held public office, shows the anger and frustration of many Americans who felt left behind by the economy and ignored by the political establishment.

The Republican candidate sealed victory when he took key battleground states Pennsylvania and Wisconsin.
The Clinton camp initially refused to throw in the towel, but Mr Trump told supporters shortly before 8am UK time: “I’ve just received a call from Secretary Clinton. She congratulated us – it’s about us – on our victory and I congratulated her and her family on a very, very hard-fought campaign.”
During the battle for the Oval Office, Mr Trump had repeatedly described his rival as “crooked Hillary” and called her a “nasty woman”.
But he struck a conciliatory tone in his first appearance as president-elect, thanking the former first lady and secretary of state for her “service” to the country.
Mr Trump sought to give reassurance to international leaders about his intentions: “I want to tell the world community that, while we will always put America’s interests first, we will deal fairly with everyone – all people and all other nations.
“We will seek common ground not hostility, partnership not conflict.”
But the markets were panicked by the Trump victory, with London’s FTSE 100 Index dropping as much as 2% on opening.
Shares also tumbled in Asia and the dollar and Mexican peso fell.
Mr Trump teased supporters with the prospect of potentially serving the maximum, two full terms as president.
He said that “at the end of two years, or three years, or four years – or maybe even eight years – you will say that so many of you worked so hard, but you will say that was something that you were really very proud to do”.
