Anti-Wall Street protesters and their supporters flooded a city park area in Portland early Sunday in defiance of an eviction order, and authorities elsewhere stepped up pressure against the demonstrators, arresting nearly two dozen.
Crowds converged on two adjacent downtown Portland parks where protesters are camped after city officials set a midnight Saturday deadline to disperse. Hours later, protesters remained though by dawn Sunday the crowd had thinned and obeyed police orders to clear the street and take down a makeshift barricades.
At one point overnight, the crowd swelled to thousands.
Organizers said they hoped enough people will join them to make it difficult if not impossible for police to carry through on any eviction.
"Occupy the street," one organizer said through a bull horn. "Remain peaceful and aware. We have strength in holding the streets."
Demonstrators had used pallets and old furniture, wood debris and even a bicycle to set up makeshift barricades on either end of a street that runs through the encampment, apparently in an attempt to block traffic. The barricades later were taken down by protesters.
