Seattle Department of Transportation crews on Tuesday began removing concrete barriers marking the entrance to the area protesters are calling the Capitol Hill Organized Protest, or CHOP.

A crew used heavy machinery to remove the concrete barriers at 10th and East Pine Street. Seattle Police officers were also at the scene to assist crews in case protesters intervened.

Protesters almost immediately began to construct a makeshift barricade to take the concrete barrier’s place, moving furniture, trash cans and plywood into the road to continue to block traffic into the area.

As of Tuesday morning, no plans had been set in place to remove the other concrete barriers in front of the abandoned East Precinct, according to Seattle Police Department Assistant Chief Adrian Diaz.

Monday marked the fourth shooting near the CHOP zone since the occupation began three weeks ago.

A 16-year-old boy was killed and a 14-year-old boy remained hospitalized in critical condition after a shooting on 12th Avenue between Pike and Pine around 3 a.m.

Seattle Police Chief Carmen Best appeared on camera later Monday to urge protesters to leave the CHOP zone, saying "Enough is enough here."

"This is something that's going to need to change," Best said. "We're asking that people remove themselves from this area for the safety of the people. If they care about people, they're going to have to try to help us to make it safe."

Best said the shooting resulted in the second death of an African-American victim "at a place where they claim to be working for Black Lives Matter.”

Horace Lorenzo Anderson, 19, was shot and killed on June 20 when a shooting rang out around 2:30 a.m. near Cal Anderson Park on 10th Avenue and East Pine Street inside the CHOP.  A second man was injured in the incident.

The fatality prompted Seattle Mayor Jenny Durkan, a Democrat, to announce last week that the city would begin efforts to dismantle the occupied zone, but the barriers and tent encampment in Cal Anderson Park remained largely in place throughout the day Monday, KING-TV reported.

A 17-year-old was also shot in the arm near Cal Anderson Park on June 21, and a man in his 30s was shot in the calf near the CHOP zone on June 23.

City efforts to dismantle the CHOP were thwarted Friday when protesters laid down in the street to block Seattle Department of Transportation crews and heavy machinery from removing barricades around the occupied zone. Crews left after two hours without removing the barricades.

The encampment in Cal Anderson Park has become more difficult to manage, drawing violence and a large homeless population since the onset of the occupation three weeks ago.

Organizers on Sunday said they’re seeking to move into the abandoned East Precinct, where most protest leadership have already taken up shelter, as part of an effort to secure their best bargaining chip in convincing city officials to act on police reform and other demands, the Seattle Times reported.

Negotiations between protesters and city officials over the weekend proved unfruitful, despite Durkan reiterating on Sunday that she outlined a plan earlier in the week to review the Seattle Police Department’s budget and allocate funds to invest in black communities.

“In recent weeks, I’ve had more than a dozen meetings with organizations, Black leaders, and protesters. Right now, I am at City Hall doing the work,” Durkan tweeted.
