Protesters took to the streets of Portland on Tuesday following news of a Wisconsin prosecutor's decision not to press charges against a White police officer accused of shooting Jacob Blake over the summer.

Dozens of demonstrators, some allegedly carrying shields and wearing gas masks, descended upon a portion of the city surrounding Portland Police Bureau’s North Precinct shortly after 9 p.m., police said in a Wednesday summary of events. 

They were reportedly protesting Wisconsin District Attorney Michael Graveley's decision not to bring charges against Kenosha Officer Rusten Sheskey, who allegedly shot Blake seven times during a domestic disturbance call Aug. 23. Blake, a Black man armed with a knife at the time of the incident, was left paralyzed from the waist down.

"People placed burning material and barricades in the streets, blocking all traffic lanes of Northeast Martin Luther King Jr. Boulevard," police said. "People sprayed graffiti on public and private buildings all along the street."

Police said officers made "some arrests" but did not immediately provide additional information.
