Comrades in Seattle built a barrier of snow to block vehicles from leaving a police precinct in Seattle on Saturday night.

One clip, posted on Instagram by “standwithseattlepd,” appears to show a police vehicle trying to leave the building before reaching the approximately 3-feet-high snow pile and rolling back down a ramp.

Around a dozen people can be seen outside the building when officers take action.

This is the same precinct that was the focal point of anti-police protests last summer. On August 24, a man allegedly attempted to set fire to the station. A month later, rioters tossed Molotov cocktails at the precinct.
