PORTLAND, Ore. (KOIN) – A group of about 40 to 50 demonstrators gathered in downtown Portland near the police bureau’s Central Precinct on Wednesday night.

The number of people in the group dwindled throughout the night. At one point, police accused the protesters of blocking entrances and exits to the building on Southwest 2nd Avenue. Officers warned people they could be subject to arrest, citation, and crowd control munitions if they continued to block access to the precinct.

The Portland Police Bureau began at 10:20 p.m., telling demonstrators to not vandalize the building and to stop blocking vehicular traffic.

A KOIN 6 News reporter at the scene saw a small trash fire set in the street that had been put out.

They also saw police in riot gear, traveling on the side of their white vans — but witnessed no interaction with the crowd. Overall, the crowd was much calmer than what the city has seen in the recent past when it comes to demonstrations.

By 11:30 p.m., only a handful of demonstrators remained near the building.

This is a developing story.
