A man was seriously injured late Sunday when protesters beat him after he crashed his truck on a downtown sidewalk, authorities said. The protesters had reportedly accused the man, who has not been identified, of trying to hit them with his vehicle before the crash.

Portland’s Police Bureau says it’s struggling to respond to 911 calls, including reports of assault, burglary and theft, as violence continues to escalate amid over 80 days of Black Lives Matter protests.

Police told the New York Post on Sunday night that dozens of people were struggling to reach 911 operators as officers were directed to quell sometimes aggressive crowds, throwing rocks and bottles at officers.

A crowd of Black Lives Matter and Antifa rioters in downtown Portland beat a white man unconscious Sunday night after dragging him from his truck, video footage of the incident shows.

The crowd surrounded the man’s white truck around 10:30 p.m. near where he crashed into a light pole at Southwest Broadway and Taylor Street. At least one individual punched him as he sat inside before he was pulled out of the vehicle.
