Police warned rioters that failure to leave the area would subject them to “citation, arrest, and/or crowd control agents, including but not limited to tear gas and/or impact weapons.”

Officers deployed in the Southeast Portland area, about six miles from downtown, were seen trying to block crowds at 47th and 53rd avenues, KGW reported.

There was no immediate information about arrests, injuries or property damage.

An earlier march to the building was turned back by police, The Associated Press reported.

The government building is located at the corner of 47th Avenue and Burnside Street in Southeast Portland. It houses offices for the Portland Police Bureau and the Multnomah County Sheriff’s Office.

Crowds arrived near the Kelly building around 11 p.m. local time, Portland’s KOIN-TV reported.

The overnight riot was declared hours after opposing groups of right-wing and left-wing agitators clashed Saturday afternoon near the Terry Schrunk Plaza in downtown Portland, just short of six miles west from the Kelly Building, across the Willamette River.

The city has seen nightly unrest for nearly three months., since the May 25 death of George Floyd in police custody in Minneapolis.
