PORTLAND, Ore. (KOIN) — Opposing protest groups gathered outside the Justice Center in downtown Portland Thursday afternoon, with at least one person being pepper-sprayed by a protester.

The small groups — on one side Back The Blue — literally stood across the street from each other for a time until they pushed other protesters into the streets. Police arrived and pushed them back on the sidewalks.

It was at that point one protester, wearing a green hat with an American flag on the front, was pepper sprayed in the face and the crowd dispersed.
