Berkeley police officers were keeping a close eye on the demonstrations, but video shared on Twitter showed shouting matches erupting and getting physical between the two groups.
Protesters threw smoke bombs into the crowd.
Police eventually moved in to make arrests around 3:15 p.m. Video showed officers on motorcycles chasing down a female protester before she was arrested.

A group of the anti-Trump protesters moved onto the street to block traffic on Martin Luther King Way at Addison Street. Pepper spray and fists were flying in the crowd.
