PORTLAND -- Shortly after Mayor Sam Adams announced the the Occupy Portland encampment would have to vacate two downtown parks by Sunday, crowds formed outside City Hall and the doors of the building were locked from the inside as a precaution.
Adams announced at 10 a.m. Thursday that protesters would no longer be allowed to camp at Chapman and Lownsdale Square parks, effective at 12:01 a.m. Sunday.
Security officials locked the doors to City Hall at around 11 a.m. as several dozen protesters began to move from the encampment to the sidewalk on the east side of the building.
Employees and people inside City Hall were allowed to leave, but people outside were not allowed in.
An Occupy Portland General Assembly meeting was moved from Schrunk Plaza to City Hall, where just after noon the number of protesters outside had swelled to an estimated 150. Members of the group said they would not leave and they burned a copy of Adams' announcement.
The group was split into committees expected to bring ideas on options to a General Assembly meeting Thursday night.
One of the protesters said Occupy groups from five cities would be coming to Portland to offer support. Another protester said that Adams had given them more time to gather and generate ideas than mayors in other cities had allowed.
Some in the crowd suggested that new camps should be dispersed throughout the city.
A long line of people spoke out at the impromptu rally, including a man who said, We will keep coming back and coming back. They will not move us.
The protesters eventually returned to their camps but one man was arrested in front of City Hall for allegedly undressing in public.
