Multiple protesters were arrested in Portland overnight after police declared an unlawful assembly during the 99th consecutive night of unrest in the city.
Chaos erupted outside the Portland Police Association building where a few hundred demonstrators gathered after marching from Kenton Park earlier Friday evening.
Crowds arrived at N Lombard Street to find cops in riot gear as well as Oregon state troopers waiting outside.
It marks the first time state police officers were back on the front lines after being withdrawn from the area early last month.

Police warned protesters to stay off the streets and private property, threatening them with citations, arrest, the use of tear gas and crowd-control agents.
The encounter led to a face off with officers, with protesters chanting and tossing balloons, Oregon Live reported.
Just before midnight, about two hours after demonstrators arrived, cops declared an unlawful assembly and began moving in on crowds, pushing people out of the area.
Clouds of smoke filled the air as cops deployed smoke bombs and stun grenades to disperse crowds.
Police ran down the street, knocking people down and arresting those who they say were not following orders.
As some people were being detained, they were pinned to the ground and blood could be seen marking the street pavement.
