PORTLAND, Ore. (AP) -- Terry Schrunk Plaza is clear Tuesday after police moved in around 4 a.m. to help Federal Protective Service officers remove Occupy Portland demonstrators.
Lt. Robert King says city officers helped the federal police arrest nine campers and remove their tents.
King says after a period of agitated tension, the situation became peaceful and most demonstrators were compliant.
Camping is not allowed in the plaza. It's federal property that closed at 10 p.m. Monday.
Camping is allowed at two nearby downtown city parks, but King says the mayor and police have been clear that the camping won't be allowed to spread to other parks.
The Occupy demonstrators were cheered Monday afternoon by activist filmmaker Michael Moore who was in Portland for a fundraiser.
