Demonstrators allegedly broke at least three glass doors and a door switch, and graffitied the rotunda at City Hall within 15 minutes of being there, according to the Oregonian.

The group also allegedly destroyed security equipment and a surveillance camera, though police reportedly were able to control the crowd and made multiple arrests, the Oregonian reported.

Tuesday marked the three month anniversary of George Floyd’s death and 90 days of consecutive protests in Portland, the Oregonian reported. Protesters reportedly gathered at a park and marched for around an hour before a crowd descended on City Hall around 9 p.m.

One demonstrator allegedly lit an aerosol can while aiming it at the building, the Oregonian reported. The protest was declared a riot by police who cited “the extreme life safety concerns” of city hall employees, according to the Oregonian.
