Several hundred Occupy Wall Street sympathizers have marched to the Bank of America Plaza in downtown Los Angeles and some have set up tents on a lawn.
Helmeted police equipped with batons have surrounded the base of the bank tower but the protest has remained peaceful.
The march began shortly after noon Thursday at the Occupy LA encampment at City Hall. Police stopped their progress down Broadway when they spilled off the sidewalk and into the street. Three people were arrested there.
Earlier Thursday, Los Angeles police arrested 23 people without incident after they sat down in a street during a peaceful rally by hundreds of people organized by labor groups who had a permit. Two other people were also arrested separately for interfering with officers.
