Sheldon High School was placed on lockdown Monday afternoon after school officials received a report that a student had been stabbed.
Principal Paula Duncan, in an update to parents, reported that the victim was transported to an area hospital for treatment. Another student was detained and was being questioned by law enforcement officers.
Sgt. Zach Hatch, Sacramento County sheriff's spokesman, said the stabbing occurred on the high school campus, but the victim, a 16-year-old boy, left campus and went to a relative's house, where the 911 call was placed. The caller said the youth was bleeding from a stab wound.
The school resource officer at the campus, a sheriff's deputy under contract to the school district, heard the 911 call and responded to the residence, Hatch said. The student's injuries were not believed to be life-threatening, he said.
Deputies went to the campus and determined that the stabbing occurred in a bathroom near the high school's gymnasium. The campus was locked down about 1:40 p.m. as a precaution. Hatch said one student was detained as a person of interest and was being questioned. Investigators, he said, were still trying to sort out what occurred and whether anyone else was involved.
Hatch said a knife is believed to have been used, but no weapon has been found.
The lockdown was lifted shortly before 3 p.m.
In her notice to parents, Duncan said, "Staff and students followed the emergency lockdown procedures and responded effectively and efficiently. All students are safe."
