SALMON CREEK, Wash. -- A 14-year-old freshman student has been arrested on suspicion of assault charges in connection to a chemical spill at Skyview High School.
The student was taken into custody on suspicion of two counts of second-degree assault and reckless endangerment. The unidentified teen is being held at Clark County Juvenile Detention Center.
Seven people were taken to the hospital on Thursday morning following the spill.
Deputies said those people suffered respiratory distress after being exposed to a noxious liquid.
Students and teachers in that wing of the school were evacuated from Skyview, located at 1300 NW 139th St., following the spill at 9:30 a.m.
Thursday afternoon, all of the four students and three adults, except for one person, had been discharged from the hospital, said Clark County sheriff's Sgt. Fred Neiman.
The spill took place after the student brought a container of bleach and ammonia to school. He showed it another student, who pushed it away, spilling the container, school officials said.
Firefighters and a hazmat team responded and directed the school to shut down the HVAC system. As of 11 a.m., a maintenance team were at the school to begin the cleanup process.
Deputies are investigating why the student brought the liquid to school; they plan to search his house, school officials said.
The Clark County Sheriff's Office's major crimes team is also investigating.
Firefighters say there is no longer a threat to students. Classes are still in session for the day; students are being allowed back into their classrooms, except for the room where the spill occurred.
