The damage was caused during the “Capitalism is Scary” march that began around 7:15 p.m. Saturday from Irving Park, Oregon Live reported.
But as the group marched south to Portland’s convention center, some of the protesters smashed the windows of buildings, including a bank, a real estate agency, two phone company stores, a hotel, and a Starbucks, the outlet reported.
The AT&T store’s windows were vandalized while a worker was inside, Oregon Live reported.
Police announced over a loudspeaker that it was declaring a riot around 7:40 p.m. and broke up the demonstrators.
“By 8:30 p.m., most of the rioters had gone and the riot declaration was rescinded,” police said.
No arrests were made, but the acts of vandalism are under investigation, authorities said.
