Ten people have been arrested in Oregon during a protest related to the police shooting in Ferguson, Missouri.
The Portland city police bureau says the arrests came last night "after a large group of protesters laid down in the street and refused lawful orders to clear the roadway".
Yesterday's gathering over the Missouri shooting death of a black man by a white police officer included a speech by the Reverend Jesse Jackson.
The Oregonian reports that Mr Jackson urged non-violence and said the resignation of the officer was "a step in the right direction," but that much remained to be done to achieve justice for the victim.
Police say that after Mr Jackson left, some protesters marched around downtown and sporadically disrupted traffic.
Officials say some bottles were thrown at officers and a police car was damaged.
The nine adults and one juvenile arrested will face charges that include disorderly conduct.
