PORTLAND, Ore. (AP) — Portland police said 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. Both groups had mostly dispersed by the time officers arrived, police said.

Windows and glass doors were broken and graffiti littered the front of various businesses, KOIN-TV reported. The Mexican consulate was also spray-painted.

The television station reported that an “autonomously organized” protest was planned for Friday night in which organizers asked protesters to be “extra angry at how PPB and other aspects of our city has oppressed trans people.”
