SEATTLE, WA — The Office of Police Accountability is investigating after two videos were shared widely online, showing Seattle police officers grabbing counterprotesters during a downtown pro-Trump march Saturday afternoon.

The first video, posted by @spekulation on Twitter Sunday night, was re-tweeted nearly 52,000 times by Tuesday evening. The clip shows an officer tripping over a bicycle before grabbing a protester. A second protester gets involved, pulling the first person by their backpack, and is taken to the ground by several officers.

A second clip posted in the thread shows a bicycle officer push past a person walking on the sidewalk before a second officer pulls the person from behind and pushes them up against a building.
