More than two dozen students have been suspended from school for 10 days after a confrontation at an eighth-grade basketball tournament exploded last week, Vancouver Public Schools officials said Monday.

Twenty-seven juveniles have undergone “emergency expulsion” so the school district can investigate their roles in what the Clark County Sheriff’s Office has described as a riot on Friday at Vancouver’s Gaiser Middle School, said Patricia Nuzzo, a school district spokeswoman. The results of the investigation could lead to more suspensions or permanent removal from school.

One of the students suspended attends school in the Evergreen School District, which also serves Vancouver, Nuzzo said. Another isn’t currently enrolled at any school and the other 25 are in the Vancouver Public Schools system.

Among the 27 are nine students who were arrested Friday at Gaiser Middle School on charges including trespass, failure to disperse, third-degree and fourth-degree assault, disorderly conduct and resisting arrest. Nuzzo said three of them were girls and six were boys. Two from the group are high school students, she said.

Sgt. Brent Wadell, a spokesperson from the Clark County Sheriff’s Office, said the arrested students were between ages 13 and 15. Neither agency released their names or specific schools or ages.

“School administrators are reviewing video of the incident and will respond with appropriate disciplinary actions,” Superintendent Steve Webb said in the statement. “The behavior displayed on Friday night will not be tolerated, and every student involved will be held accountable.”

Nuzzo said the school district identifies the suspensions as “emergency expulsions,” but they mean that a student is immediately banned from Vancouver Public Schools campuses for 10 days.

On Friday, after a student confronted another student in the stands, district security officers “moved immediately to remove the students from the gym,” the district said.

As security staff took the students out of the gym, several students began to follow them into a hallway and “interfered” with the removal, the statement said.

Things escalated as the group moved outside and the crowd, comprised of students from multiple schools in the Vancouver district, “continued to interfere with the actions of security staff,” according to officials.

At that point, security officers called the Clark County Sheriff’s Office, canceled the tournament and asked all students to leave, Nuzzo said.

The students were shouting and refusing to leave as the crowd continued to grow, the district said.

At least 60 students closed in around three deputies and a staff member at one point -- cursing, yelling racial slurs and threatening to kill officials, the Clark County Sheriff’s Office said on the night of the confrontation.

The Sheriff Office said about 33 officers were called to the scene.

Vancouver Public Schools sent an email to parents of middle school students Monday about the confrontation.

Nuzzo said the 27 suspended students were seen on video inciting the confrontation. She said the school has four cameras in the back, three in the front and one in the gym.
