Portland protest at union building declared as riot

A riot was again declared by authorities Sunday night in Portland when protesters marched to a police union building, blocked a road and set dumpster fires as officers work to quell nightly unrest in Oregon's largest city.

The protest was over almost as soon as it began outside the Portland Police Association building - the same building where protesters were dispersed after a fire was started inside the offices the night before.

Demonstrators Sunday night marched to the building from a park a few blocks away. The road was blocked with fencing, and flames were seen rising from dumpsters in the middle of the street.

The Portland Police Association is a labor union that represents members of the Portland Police Bureau.

Police forced a couple hundred protesters away from the building, and live video showed several people being detained. It's unclear how many may have been arrested.

Since George Floyd was killed in Minneapolis, protests have occurred nightly in the city for more than 70 days.

Demonstrations this past week have been violent. Many in the city had hoped for calm after federal agents withdrew more than a week ago.
