WATCH: Portland protest turns violent, brutal assault caught on video

Violence erupted in Portland late Sunday just blocks from the federal courthouse after the driver of a pickup truck crashed, was reportedly pulled from the vehicle and then brutally beaten by a mob after a confrontation with protesters.

Videos that emerged from the scene were chilling. The man identified as the driver could be seen getting punched, kicked and ordered not to leave in the middle of a city street. The man in the video, at one point, appeared dazed after the initial assault, but suffered the worst blow when he absorbed a roundhouse kick to the side of the head.

Portland police told Fox News in an email that officers responded to a report of an injured person at Southwest Broadway and Southwest Taylor Street at about 10:30 p.m.

Sgt. Kevin Allen, a police spokesman, said reports indicate that protesters "were chasing the truck before it crashed, and they assaulted the driver after the crash."
