Protesters have set up barricades around the abandoned Seattle Police Department's East Precinct, establishing the so-called "Free Capitol Hill Zone", or "Capitol Hill Autonomous Zone" in the vicinity.
Footage circulating on social media shows the barricaded zone with "Cops Free Zone" and "Black Lives Matter" painted on the blocks. Another sign said, "You're now leaving the USA" and "entering the "Capitol Hill Autonomous Zone".
Another footage shows protesters cheering along with someone playing the flute. A band was captured giving a "concert" at 11th & Pike late in the evening.
Police later removed sections of the barricades but most of them remained after "negotiations" with the protesters.
A citizen, apparently a protester or one of their supporters, claimed local businesses and residents agreed to retreat from the area, calling it a "flux state in the making".
On Monday, the Seattle Police Department ordered its staff to unblock the streets to allow protesters to march their way to Capitol Hill. Earlier, Democratic Mayor Jenny Durkan also issued a 30-day ban on using tear gas in the city.
The United States has been gripped by protests since the death of Minneapolis black man George Floyd following police custody. The four arresting officers were fired in connection with the incident. One has been charged with second-degree and third-degree murder and manslaughter while the other three have been charged with aiding and abetting murder and manslaughter.
