A campus police officer shot a Hug High School student who allegedly had a knife and “tried to attack others.”

According to the Reno Gazette-Journal, the officer who intervened in the 11:25 a.m., December 7, incident was a Washoe County School District police officer. The school was locked down following the incident “as police went room to room accounting for all students and finding witnesses.”

The student who was allegedly wielding the knife is listed in critical condition.

Reno Police Chief Jason Soto said the incident began as “an altercation between two students.” One of the two students then pulled a knife and “tried to attack others.” Soto said the campus officer intervened at that point and “told the student to drop the knife.” When the student refused compliance, the officer fired.

Washoe County School District placed all schools on a two-hour delay for the start of classes on December 8.

An investigation is ongoing.
