PORTLAND, Ore. (AP) — Portland police say two separate groups of people vandalized buildings across the city. The incidents on Friday involved one group of nearly 50 people that vandalized several businesses in the northeast of the city while another group of people dressed in black and wearing spray-painted helmets gathered in the city’s southwest. No arrests were made in either group. Police say both groups had mostly dispersed by the time officers arrived. KOIN-TV reported that windows and glass doors were broken and graffiti littered the front of various businesses. The Mexican consulate was also spray-painted.
