4 arrested in NE Portland protest over Wisconsin decision in Jacob Blake shooting case Updated Jan 06, 2021; Facebook Share Four people were arrested in Northeast Portland during a demonstration organized Tuesday after no charges were filed against a white Wisconsin police officer who shot a Black man in the back last summer. Demonstrators gathered near the Portland Police Bureau’s North Precinct on Tuesday night, blocking traffic on Northeast Martin Luther King Jr. Boulevard, according to police. Some people in the crowd lit fires in two dumpsters and sprayed graffiti on public and private buildings, police said. Some in the group destroyed precinct security cameras, tore electrical wires from exterior walls and threw objects — including glass bottles and paint — at officers, police said. At least one person used spikes that damaged police vehicle tires.
