Update, 2:47 p.m., Saturday, April 15:
Police have arrested 13 people and say they "anticipate more" after violence broke out at a pro-Trump demonstration in downtown Berkeley on Saturday.
About 200 supporters and protesters of President Donald Trump gathered at Berkeley's Martin Luther King Jr. Civic Center Park when several people started pushing each other. Dozens of police officers in riot gear were standing nearby and quickly arrested one man.
Others were arrested after several fistfights broke out between gatherers for the so-called “Patriots Day” demonstration and “Antifa” counterprotest. At 1:48 p.m., police said there were a number of large fights, some property damage and numerous projectiles being thrown -- including fireworks.
