Seattle police have moved in to break up the Capitol Hill Occupied Protest (CHOP) after Mayor Jenny Durkan issued an executive order early Wednesday morning declaring the gathering illegal.

According to the Seattle Times and KOMO-TV, about a dozen protesters were arrested Wednesday morning as police ordered those present to leave the area.

Demonstrators have occupied the Capitol Hill neighborhood of Seattle for about three weeks. The protesters moved in earlier this month after police abandoned the department's East Precinct — which is located in the neighborhood — over fears of riots.

While the occupation was largely peaceful for several weeks, the area has seen four shootings since June 20, some of them deadly.

The protests began in the wake of the death of George Floyd, and were part of a nationwide protest movement against systemic racism and police brutality.

Last month, CHOP leadership released a list of demands calling for the abolishment of the Seattle Police Department, a retrial for all people of color serving prison sentences for violent crime and the de-gentrification of the city, among other demands.
